Let’s do the math....LA to SF is roughly 380 miles.
If you go 380 mph it will take one hour.
To make the trip in 30 minutes you must double the speed. Time to accelerate and decelerate would be included so the trip would hit speeds of 900 mph. Do ya think?
Has anyone considered moving at supersonic speed in a tunnel??
Also, let’s talk about the San Andreas fault. NAH!
Maybe we shouldn’t talk about this foolish idea and talk about getting water to the valley.
CA is a disaster, why double down with crap like this?
Even flying isn't practical, you pay to park at home airport, and have to rent a car in San Francisco plus having to put up with the airline schedule.
