The question is whether it really is the right answer to invest enormous sums of money and infrastructure into enabling rich people to have electric vehicles, or does it make more sense to just... not. Don't upgrade onstreet parking, take the money and build a bus service, a train service etc. Cars are fundamentally a non-scalable solution for dense urban areas. They're just really inefficient and if you're living in a city where you can only get onstreet parking you're probably better of taking a bus or a train to get around anyway. It's also a massive bonus for everyone between you and where you want to commute that they don't have to deal with your traffic anymore.

London has already made this decision - they go out of their way to make it uneconomical to drive in London. Why suddenly unlearn everything about public transport.
