Although looking at the logo now, it almost looks like we were bidding for the 2206 games - unlikely there will be much snow left by then, but on the plus side, Slussen might be finished!

A map showing some of the infrastructure planned in Stockholm for the 2026 games. Several projects still under construction would likely have been accelerated including the metro lines to Barkaby and Arenastaden, and perhaps the major project at Slussen

With the Winter Olympics opening in Milan I am reminded that one of the last things I worked on before leaving the City of Stockholm was our unsuccessful 2026 bid.

I wonder how many ongoing infrastructure projects would have been accelerated if weโ€™d won?

(Also, our logo was clearly superior!)

Self-driving taxis are coming to London โ€“ should we be worried? | Jack Stilgoe Waymoโ€™s cars were first rolled out in San Francisco, but the English capitalโ€™s old roads, pelican crossings and jaywalkers may pose issues for AI, says science and technology professor Jack Stilgoe

โ€œJaywalking is permitted in London. In 1966, the police tried to crack down on it, but gave up after three months.โ€

People walk and cycle on roads by right, people drive under licence.

Jaywalking is not a thing in English law and Waymo must not change that.

Interesting contrast in coverage: a misleading, vested-interest report suggesting heat pumps raise UK bills made headlines.

Our peer-reviewed UK research showing high real-world efficiency across hundreds of homes was largely ignored by the media.

Big moment for Europe: in December, fully electric cars outsold petrol-only cars in the EU for the first time.

This shows that clear, consistent policy works. Which is exactly why backtracking now would be a mistake. Rolling back targets or creating uncertainty would slow investment and innovation.

...engineers are problem solvers - you just need to give them the right problem to solve. That meant working with them to define the right essay question based on political direction. (That and that fewer cars means more work for signal engineers, not less -> they were worried about their jobs)

This may well come as a shock to many Stockholmers but the scale and coverage of our transit system compares well to some of the worldโ€™s most dense. Itโ€™s less of a surprise to those of us who have worked hard to make it happen!

(Could it be cheaper and more reliable? Absolutely!)

I am also reminded by these graphs that the Norwegian word for a non-electric car is "fossil car". Perhaps we should all adopt that term, now that the short form acronym for Internal Combustion Engine is so strongly associated with something far more sinister.

It is noticeably quieter and there is no diesel smell that otherwise tends to hang around in the cold air.

Someone said they thought the snow stayed whiter because of the EVs. I am skeptical, I would imagine that's more to do with tyre wear - but less traffic in the centre almost certainly helps

As a Stockholmer this is not easy to admit but visiting Oslo feels - at least from a transport perspective - a bit like visiting the future:
- car traffic is barely increasing despite population growth
- transit, walking & cycling is handling all of the growth
- 95% of new cars are electric
