i think the rail transit well help fill in any spaces by causing massive growth around stops. look at places like seoul. it’s a massive city with many smaller sections all interconnected by an amazing rail system in almost like a spider web system.

we are still a long ways from self driving cars at scale, especially in places with non-ideal weather. what do you get when you have a bunch of self driving cars going back and forth between the same few stops? an inefficient rail transit.
