I don't blame them, housing a car seems rather wasteful, doubly so if there's a perfectly usable driveway. It'll be interesting to see how Bay Area municipalities update their building codes if cars-as-a-service ever takes hold.
Not if you live anywhere with a significant amount of snow in the winter... Especially if the local municipal authorities combat that snow on the roads with absurd amounts of salt.
I should say, I have a car, but we use it for leaving town, not <1 mile trips within it.
I said nothing about whether a car is a choice or a necessity. That would depend on where you live also, but for different reasons.
I only said that it is not wasteful to house a car under the following circumstances: in the winter, where there is a lot of snow, and where the local municipality dumps salt on the roads throughout the winter (which gathers on surface of the car, including exposed components beneath).
