> For example, in the bay area, parking in SF is difficult to say the least and usually in paid garages I think it's useful to consider that SF downtown parking is - in the grand scheme of things - an exception, not a norm. As it turns out, parking is free in most geographical locations. Even within SF, there's plenty of free street parking around areas like the Sunset or Potrero Hill for example, a mere 20 mins away from downtown core. Go another 15 mins further south and there's free parking at Home Depot, Costco, etc. Go further out to places like San Jose, and strip malls with abundant free parking dominate the landscape. IMHO it doesn't make sense to think parking space can be easily replaced with residential space. This has been a theme in places like downtown Toronto, where parking lots were literally getting turned into condo buildings. Without a supporting transportation strategy, all that ends up happening is overloaded roads because more residences equal more people, and people need transportation. Going back to Toronto, they're now apparently talking about expropriating businesses to make space for public transit expansion in the worst congested subway station (Ironically, several businesses were already displaced from a lot to build a high rise mix use condo building in this exact intersection some 5 years ago, and there's now another high rise in construction right across the street from it). I honestly wish them good luck with scaling public transit to match demand, as all forms of traffic there - including the subway - already get to pretty bad levels.
