It'd be a good start!

It'll take a massive increase in public transportation infrastructure, and a long and slow redesign of our cities and how we live to fix the mess the auto-industry has put us in. It's a transition that's long overdue, but the reality of the situation now is that people still need their cars.

Making sure that people have something to fall back on before we take their cars away from them or remove the places they put them at night/charge them should be a priority. What these cities are doing is the opposite of that.

Many households have more than one car per driver. With WFH many of these cars sit largely unused. We went down to being a one car family over a year ago and it has rarely been an issue. It requires a little bit of planning. "Hey I need the car on Thursday. Does that work for you?" Otherwise, a second car would mostly only get used because "Well, it hasn't been driven in a while".

I agree that WFH is a game changer here. Households in that situation are incentivized to get rid of excess vehicles since they cost money to maintain, license, and insure. With downtown office spaces and the nearby businesses that depend on them being abandoned, a lot of parking space can be reclaimed there too.
