It’s an interesting thesis. I might be supportive of this if changes were planned properly – for safety, transport, infrastructure, etc. Basically simcity – the heck of out it.
It’s a better plan than the current High Speed Rail plan.
If you could just build the HSR without worrying about EIR or eminent domain, the entire SF-SD segment could be done in about 10 years.
Housing and transport would be a lot better in CA if you could build high density housing high rises near mass transit.
