I had to sigh heavily when I saw this tweet from Prime Minister Rishi Sunak with its pledge to “End Labour’s unfair ULEZ Expansion”.
Just last month, Sadiq Khan won a resounding victory in the Mayor of London elections, an election that had come to be seen as a referendum on ULEZ.
At the time, I revisited the Department for Transport data for the third time and established that between March 2022 and September 2023 there was a 40% reduction in the most problematic private cars. To my mind that makes ULEZ a successful policy intervention. It also means that the incumbent government is campaigning on the basis of something that affects just 331,632 private cars in London, a city of 9 million.
Well, it affected 331,632 private cars by the end of September 2023. I asked ChatGPT to help me with the linear regression and it told me this month, June 2024, the figure will probably be 230,000.
I wonder how many policies have generated so much airtime for such a small proportion of the population. It is deeply perplexing that ULEZ has worked its way into our national psyche (not to mention the time I’ve spent looking at it myself!)
