This has been a growing trend in the US. The old argument for rules like this was often "broke cars reduce home value", so it's fun to try and see them use the pro-environment card but it's really to push out poor people. Every once in a while there's a city that makes a move like this because they are tired of broken down cars in poor neighborhoods and then end up repealing the rule when cops get uppity and apply it to middle/upper class people who are doing vehicle restorations in their driveways.

The big bummer in rules like this is that the wealthy people in office that are enacting this legislation don't know what a "major" car repair is because they've never done any. And their definition of a 'special tool' is anything beyond their Craftsmen "Baby's First Toolbox".
