Railing against Khan because of the pointless ULEZ expansion misses the point.
ULEZ is Tory government policy. TfL funding is linked to its expansion, which Grant Shapps pushed for.
Rishi Sunak and his "Conservative" party could get rid of ULEZ but they won't because it's party policy that they all support. They are all wedded to the nuttery that is Net Zero.
This is yet another reason why the fake "Conservative" party must be booted out at the next election, followed by the "Labour" party thereafter. Hopefully then we will have our revolution.
