Probably cars overhanging the pavement, its a big no no in most London Boroughs as a high number of lorry drivers have found out if even an inch of tyre is imposed on the path when parked up.
Got to get the revenues in from someone, might as well be the evil motorist, dropped kerb or not hundreds of thousands of off street parking where people have concreted over small frontages the modern car is too long to fit.
Live and let live is history.
This sort of thing coming to all of us in due course as they do their best to make it increasingly difficult/expensive for working class people to own their own private cars, it isn’t the case they’re trying to force us into electric cars either, the working classes arn’t part of the wonderful green utopia they have planned but haven’t twigged it yet, you won’t find actions like this in well heeled parts of the home counties commuter belts where our betters reside in walled gated exclusivity.
