AI drives software productivity – and challenges – for Motorway | Computer Weekly
For decades, engineering teams treated code like a vintage Ferrari – expensive to build, painstakingly maintained and too precious to ever throw away. Every line represented a significant investment of human capital and time, and has led to a culture where code was cherished and its longevity was a marker of success.
But at the AWS Summit in London this week, Ryan Cormack, principal engineer at online used car marketplace Motorway, consigned that philosophy to the scrapyard. In the age of agentic artificial intelligence (AI-)driven software development, he says, engineering teams can become more productive and are able to build, revise and maintain code at speeds previously unthinkable.
In this article, we look at Motorway’s radical shift from manual coding to an AI-first development pipeline powered by AWS Kiro. Cormack talks about how the company achieved a 4x increase in engineering output, the challenges that come with the ability to produce more code, why the future of software development lies in treating code as disposable, and the core benefits of codifying organisational culture into AI steering files.
The mindset shift: Disposability vs polish
The most profound change at Motorway is speed of delivery but also a psychological break from the past. Historically, writing code was a “time-expensive process”, Cormack says, adding: “We wanted to have code that was so good that we could cherish it for years to come, because we had invested so much time into making it.”
But since starting to use Kiro – AWS’s agentic AI-capable IDE – that mindset became a bottleneck. “We shifted away from, ‘We need the most well-polished code for every line we write, all the time’, because we can rewrite it again tomorrow at a speed that’s never been possible before,” says Cormack.
This has led to a strategy of “evaluation over production”. Motorway now generates vast amounts of code – a million lines a month – much of which may never reach a customer, says Cormack. Instead, it is used to test and evaluate multiple different ways to solve a problem before committing to it.
The lesson for other organisations is clear. Don’t aim for a perfect first pass. Use AI to cycle through iterations, then use human expertise to refine exactly what you want from the options the AI helps provide.
Managing the ‘volume crisis’: Rigour over speed
While a 4x increase in output sounds like an engineering dream, it creates a real “review bottleneck”. If you write 400% more code but maintain 100% manual review processes, the system collapses. To combat this, Motorway hollowed out the “manual middle” of the development process and moved human energy to the ends of the process – namely, the spec and the review.
“We find ourselves spending more time planning code and the whole process up front, and a little bit more time reviewing what comes out,” Cormack says. “But we lose all this time in the middle where we previously had to manually write all the code.”
To ensure AI doesn’t just produce any code but “Motorway code”, the team utilises “steering files”. These files augment the AI’s system prompts with the company’s specific DNA. They are specific to Kiro and are markdown documents that contain instructions, standards and preferences to guide the AI behaviour and coding style.
They include, for example, naming conventions that standardise how application programming interfaces (APIs) are labelled across Motorway’s 7,500-dealer network, and design patterns that enforce specific software architectures.
By injecting these rules via the AI, generated code looks and feels like it was written by a veteran Motorway engineer.
And AI isn’t just used for the build; it’s used for the full lifecycle. “We need to use AI to help us debug, analyse, understand, and evaluate systems as they run,” Cormack adds, noting that agents now monitor logs and metrics to help humans manage a massive fleet of services.
The ‘Kiro’ engine and model agnosticism
A critical component of Motorway’s success is that Kiro acts as an agentic loop rather than just a simple “autocomplete” tool.
“Kiro knows how our CI pipelines work,” says Cormack. “It knows how our infrastructure is code-driven and it knows how our internal applications work together. It’s able to help guide us every step of the way.
“We’re using Kiro across our full software development lifecycle. Our product and UX teams can ship real prototypes into our customers’ hands quicker than we’ve ever been able to before. What would take weeks now takes hours.”
His team can leverage its model agnosticism too. Cormack explained they aren’t locked into a single LLM: “We use Kiro with Claude’s latest Opus 4.7 model, we use it with some of the open weight models, things like Meta’s Llama models … we’re able to selectively pick the LLM that we know is going to be able to best perform the specific task.”
This flexibility helps to mitigate the risk of hallucinations. Motorway relies on a spec-driven approach where the AI must think through the problem and generate a technical design before writing a single line.
“It will help us write automated tests that are able to prove that each of these points has been accurately done,” Cormack says. This means the AI provides its own proof of work before a human ever touches it.
Legacy transition from Heroku to AWS
Motorway wasn’t always this agile. The company was “born in the cloud”, on Heroku, which Cormack acknowledges was “great for scaling and getting going”. But as the company grew, it hit friction points.
The transition to AWS was driven by a need for “flexibility, adaptability, and scalability”, says Cormack, who views their Kiro-enabled AI-first pipeline as the ultimate tool for such transitions.
If he were to do things all over again, Cormack says he would “adopt this model of thinking much earlier on”. The ability to use AI to map migration logic and service dependencies would have saved months of manual effort during the move off their legacy platform, he believes.
Lessons for the boardroom
For organisations that want to replicate Motorway’s 250% increase in deployment frequency, Cormack warns against automating the grind of coding without also automating the rigour of testing.
“If you try to build just by writing code faster, it doesn’t solve the problems,” he says. “I don’t think our customers necessarily want code; they want features and functionality.”
The winners of the AI era won’t be the ones who write the most code, but the ones who build the most rigorous frameworks to manage its disposability.
As Cormack says: “Kiro’s now writing over a million lines of code for us every single month. So, before we start any new piece of work, our engineering team chooses Kiro to help understand exactly what it is that we want to build.
“The rigour at the start of this process helps enable the precision we want in our engineering at the end. So, every piece of work that we do starts with a spec, understanding the intent of what it is that we’re building and why.”

Port of Tyne advances connected mobility, autonomous logistics | Computer Weekly
The North East Automotive Alliance (NEAA), alongside the Port of Tyne, autonomous driving technology provider Oxa and a consortium of leading industry and academic partners, has delivered the Port‑Connected and Automated Logistics (P-CAL) project.
The Port of Tyne is one of the UK’s major deep-sea ports handling specialised bulk and containerised products, alongside delivery logistics, and assisting growing passenger numbers via its International Passenger Terminal.
Overall, the Port of Tyne adds £658m to the local economy, supporting 10,400 jobs directly and indirectly, and as one of the UK’s largest trust ports. Fully self-financing, it runs on a commercial basis, reinvesting all of its profits back into facilities along the River Tyne for the benefit of the North East and its stakeholders.
Delivered and funded through the UK government’s CAM [Connected and Automated Mobility] Pathfinder programme, NEAA – a collaborative, industry-led cluster dedicated to fostering a competitive and sustainable environment for businesses – is working with its partners to deliver P-CAL to demonstrate autonomous container transport at the Port of Tyne. The initiative will see the deployment of a fully autonomous terminal tractor and secure mesh communication network to move containers between the dockside and the container compound, creating a UK first in waterside port automation.
P-CAL was designed to push the boundaries of autonomous logistics by deploying and validating a fully autonomous terminal tractor in a live port environment. Building on the North East’s earlier 5G CAL and V‑CAL initiatives – which looked to assess the commercial viability of deploying autonomous yard tractors on the Vantec-Nissan route in Sunderland – the project worked to move autonomous technology from proof‑of‑concept trials into a complex, safety‑critical, real‑world operational setting.
Over the course of the project, the consortium is said to have successfully designed, integrated and tested an autonomous container transport service capable of operating on a busy quayside. The scope of work included the deployment of a fully autonomous terminal tractor; a resilient mesh communication network; the capability to integrate with terminal operating systems; real‑time coordination with live crane movements; and the implementation of a cyber security framework to enable safe, remote and automated operations.
The system was developed and tested in a newly defined and highly complex operational design domain. This is said to reflect the realities of a working port environment where traffic density, variable conditions and human interaction present unique challenges.
The regional and national partnership delivering the project combined expertise across autonomous systems, logistics, cyber security, academia, legal compliance and industrial operations. The consortium believes its project has generated valuable technical, operational and regulatory insight that will inform the future deployment of CAM services across ports, logistics hubs and industrial sites nationwide.
By augmenting the capability of the existing workforce, it says it has shown that autonomous systems can take on repetitive or more hazardous tasks, allowing skilled workers to focus on higher-value roles. This is seen as particularly vital for the North East, ensuring the region remains at the forefront of industrial evolution while creating a more resilient and tech-enabled labour market.
“Delivering autonomous logistics in a live port environment has been a major step forward for the sector,” said Graeme Hardie, operations director at the Port of Tyne. “P-CAL has shown what’s possible when innovation is applied to real operational challenges, improving safety, efficiency and sustainability. The Port of Tyne is proud to have played a leading role in a project that will influence how ports across the UK and beyond approach automation.”
Oxa founder and CEO Paul Newman added: “The success of P-CAL proves how autonomy will enable the future of resilient logistics operations. Through the project, we’ve demonstrated that existing work vehicles can be turned into a digital workforce – successfully completing autonomous container movements in a dynamic quayside environment, while providing worksite intelligence necessary for real-time industrial optimisation. P-CAL provides a blueprint for how ports and industrial hubs worldwide can deploy autonomous technology to drive productivity, efficiency and safety.”
CAM Pathfinder is funded by the UK government, delivered by the Department for Business and Trade in partnership with automated mobility firm Zenzic and Innovate UK, the UK’s national innovation agency.
Zenzic programme director Mark Cracknell said: “P-CAL is a strong example of how government and industry can work together to accelerate the commercial readiness of CAM technologies. Projects like this are vital in turning innovation into deployment, creating high‑value jobs and ensuring the UK remains globally competitive in connected and automated mobility. As the project closes, the outcomes and learning from P-CAL will continue to shape future CAM initiatives, investment opportunities and policy development, both regionally and nationally.”
The next phase of the project will examine how the system performs across broader port operations, including the added pressures of multiple vehicles working alongside people, equipment and live commercial activity.

‘STAGED’: Conspiracy Theories Are Everywhere Following White House Correspondents’ Dinner Shooting
In the immediate aftermath of the attack on the White House Correspondents’ Dinner on Saturday night, influencers, pundits, and random posters lit up social media platforms like X, Bluesky, and Instagram with conspiracy theories about the attack and the alleged shooter.
Both left and right-wing accounts claimed, without evidence, that the attack was staged.
President Donald Trump, Vice President JD Vance, and dozens of other high-profile administration officials and journalists were attending the dinner at the Hilton hotel in Washington, DC, when a suspect, later identified by media reports as Cole Tomas Allen from California, allegedly ran past security towards the event. He was detained by law enforcement while the president and vice president were evacuated. Police said that they believe Cole acted alone, but did not expand on who his intended target was or what his motive may have been. “We believe the suspect was targeting administration officials,” acting attorney general Todd Blanche told NBC’s Meet the Press on Sunday morning.
On Bluesky, which has a predominantly left-leaning user base, many people simply wrote the word “STAGED” over and over again, echoing the response to the Trump assassination attempt in Butler, Pennsylvania in 2024.
On X, many claimed the shooting was staged as a way to bolster support for Trump’s plan to build a new ballroom in the White House. The president referenced the ballroom in a press conference after the incident and a Truth Social post on Sunday morning. Many prominent online Trump boosters echoed the need for the ballroom, including far-right podcaster Jack Posobiec, Libs of TikTok creator Chaya Raichik, and Tom Fitton, the right-wing activist who runs Judicial Watch.
Their quick response, conspiracy theorists claimed, was evidence of a coordinated campaign following the shooting. “Is this another staged event,” one X user asked in a post that has been viewed more than 5 million times.
Other social media users who claimed the incident was staged pointed to a Fox News clip that featured the station’s White House correspondent Aishah Hasnie speaking from the Hilton hotel. Hasnie told viewers that prior to the shooting, press secretary Karoline Leavitt’s husband allegedly told her “you need to be very safe,” before the call was cut off.
“Fox News just cut one of their reporters off as they seemed to indicate the shooting was a pre-planned false flag,” one X user wrote in a post that has been viewed more than 2 million times. Hasnie later clarified in an X post that her cell service had cut out in a location with notoriously bad service, adding: “He was telling me to be careful with my own safety because the world is crazy. He was expressing his concern for my safety.”
“I don’t want to be fomenting conspiracies,” wrote Angelo Carusone, the chair and president of Media Matters, on Bluesky about the Fox News interview. “But I mean…this was super weird. Super weird.”
Leavitt herself was also the focus of conspiracy theories after she said “shots will be fired” in an interview ahead of the dinner, referring to the jokes Trump was scheduled to deliver. Following the attack, X users claimed the comment was “strange,” “sus,” or a “curious choice of words,” while sharing memes that suggested the shooting was staged. At least one mainstream outlet appeared to amplify the conspiracy theory as well, describing Leavitt’s comment as “eerie” and “bizarre.”

Your Kindle Is Better With Accessories. Here’s Where to Start
Kindle Holders
Hate holding up your Kindle? Or struggle with chronic pain that makes holding it feel terrible? These holders will literally take the weight out of your hands.
A Freestanding Charger
Looking to keep your Kindle charged without adding another cord to the floor of your desk or bedside table? Same. Here’s a more stylish solution if you have one of the Signature editions.
A Kindle Page Turner
The hottest new item to get as a Kindle lover is a page turner. They’re especially handy for holders like the ones above, where your hands aren’t already on the device, and can make for a great accessibility accessory for readers with different needs.
My biggest irritation with these devices so far is that you have to charge them both individually, and if one runs out of battery, the whole thing is useless. I also don’t love that the turner does tend to block at least one letter while I read, and you can’t place it on the lower or upper margins since it’ll activate the menus instead of turning the page. Still, it makes reading ultra comfortable, especially for my strained wrists.
Here’s my favorite one so far, that’s been solid at holding a charge, and next I’m testing this remote ($15) with a wearable ring clicker instead of a remote.
