I read an article back in March ? abour Mr Khan hinting at a pay per mile, or pay per minute scheme to replace the ULEZ scheme.
As more Londoners purchase ULEZ compliant vehicles, the revenue will decrease, which goes towards funding TFL, and also the number of vehicles will increase.
So they will need to raise revenue somehow and also keep traffic levels down to stop congestion. They have been looking at different models around the world, but he said they havent found a sutiable one as yet.
Regarding the LEZ charge, if they really wantd to significantly reduce pollution they would just ban non compliant vehicles, rather than impose a charge and allow the polution in. Due to the high charge they are efectively trying to do it anyway, so why not just ban them completely ?
The Gov. will probably bring in something similar eventually, as they were concerned when we all have EV, the roads will become more congested as we can all drive more due to cheaper running costs. Its not going to be painless, and they probably wont let us get away with paying less
