You say "entering the city" but it literally applies to people who live there. My old car would have cost me every use even if all I did was move it to respect a temporary parking restriction. It isn't about dislike, it is financial hardship largely affecting those of more limited means (hint, old cars).

I am fine with ulez, but it is really important to be clear that people do suffer for it. Not out of towners. Real Londoners - especially with the extension to the outer boroughs.
