Yeah, garages is one idea, but that's a land use matter of importance re: need for residential development. Garages have been proposed, but difficult to squeeze in among the competing needs. Sometimes the conflicts are just hard to resolve with the various constituencies fighting it out.
Well, yeah, I'll admit some bias here - I think cars are a cancer to cities that destroy them. I've never met anyone complaining about a lack of parking unless they were complaining about a lack of free parking. Of course, I think we could use that land as places for humans to sleep instead of cars, but I digress.
When presented with the true cost of driving, most people choose other modes. Driving and car ownership are ridiculously expensive once you realize how much you're paying for "free" parking (higher rent), "free" roads (higher taxes), and of course tens of thousands of dead people per year in the US alone. What we do now is largely force people to pay whether they drive or not, which of course encourages car ownership.
I mean, a helicopter would be a fun way to get to work but that doesn't mean we expect free helipads everywhere.
