We weren't? Well it's my favorite subject anyway.
One way to deal with urban parking problems is to build massive underground parking garages. This is very expensive. It's also what a lot of European cities did. If you aren't aware of them, or aren't looking for them, you might not notice them and you certainly won't know how large they are. But some European cities have absolutely massive underground parking caverns, sometimes under your favorite tourist sites and monuments. For example, there are 2100 spots under Villa Borghese in Rome.
I'm sure it cost an immense amount of money. It wouldn't be my favorite use of public money. But it was a smarter way to deal with the rise of the automobile than knocking down every building in sight to build surface lots/overground parking structures to support the few buildings left intact.
