Have any of the fatal flaws been fixed (sub-1000 person per hour transport volume, rail can move 20k an hour, 1 lane road moves 2k per hour), or has Elon revised his inaccurate estimate, where he estimated SF to LA rail without actually crossing the bay into SF (or acquiring the right of way), or going into LA?
I recently drove through both cities, and where Elon proposed to end the alignment would make it absolutely useless for most potential users at peak hours, as its a 2+hr drive across LA and out of it to get there. Combined with where it terminates near SF, you could spend a few hours just commuting to & from it.
Ultimately, there isn't any way to get around the topography of either city whereby you can avoid the issues California's High Speed Rail has run into. Your gonna end up with lots of landowners, large and small, pissed off that your taking their parking space (which is on railroad property, and they've been using for a few years illicitly), changing the neighborhood, or doing anything at all. This is a costly process, but you either build it now and get the right of way, or you leave it to happen 40 years from now at a much higher cost.
