I remember the first time I was sent to the Bay Area for training. I was excited to see this City of Mountain View I'd heard so much about; to explore its city nightlife and enjoy the view of the mountain. My boss had to let me down gently :) "Mountain View in Europe would be called a village", he said.
I don’t know how quickly we’ll find the political will to break that since everyone who owns property in a city has a financial incentive to keep prices artificially high. Removing density restrictions helps by making redevelopment financially advantageous for individuals but the degree of uncertainty we have now is going to slow that down, too.
The big problem with changes like this (which I support, btw) is that the changes get immediately reflected in land prices, which means that you basically can only put the maximum number of units on the land, which tends to increase prices.
If you build enough, this doesn't happen but I don't think any western urban area is anywhere close to that point.
But when I think of “suburbia” I think of a series of housing developments, strip malls p, golf courses just off all major highways/roads. Cul de sacs as opposed to grid pattern. Generally hostile to pedestrians getting fro residential to commercial and business areas. On,y part of the Valley is like this, mostly the richer areas more towards 280, such as Los Altos, Portola Valley, Cupertino.
I guess this is reflective of US/Europe suburbia. From my (Irish) perspective, the valley is clearly suburbia given the density. I'll never forget taking the caltrain from Palo Alto to SF and seeing basically low-density housing with sporadic strips of shops. That would be clearly suburban to me (but obviously other people's opinions will differ).
Plenty of large corporations have headquarters in suburbs (where the rich execs want mansions) but in a close enough commute to a major city where more of the employees want to live.
