TfL also revealed that it expects to generate far less money than anticipated from the expansion of the ultra-low emission zone because more drivers than expected have switched to cleaner cars to evade the £12.50 levy. It was expected to generate up to £2m a day (£730m a year) but that has been downgraded to £600m over three years instead of £2190m. Therefore is a hole in the TfL budget of £1590m over 3 years.

So TfL and the mayor expected the ULEZ to be a money making scheme, with people not being bothered about the environment but it has backfired as people instead have decided that emissions are a bad thing and have decided to get newer vehicles.

TfL & the mayor couldn't run a bath, and we are stuck with the current mayor of London for another few years.
