Not suitable in Los Angeles. We have some mass transit but the "homeless" use it for shelter and make it dangerous for others to use. Besides, I prefer the comfort of my own car. We need to vote these climate cultists out.
The problem is transit systems need to be good to get people to use them.
Consider a city I've been in many times that has a transit system that does work: Shanghai. Walking + subway almost always beats any other means of reaching anything that's not local. The bus stops are farther apart which means a bit more walking--but it also means buses aren't that much slower than cars. And the vast majority of people pay by means of RFID stored value cards--no messing with change or anything, if you're used to the system you can pay your fare while simply walking past the machine. Detection is basically instant if you get the card close enough to the scanner, no issues of alignment or anything and it doesn't even need to be exposed.. It just works. The same cards work on the subways, you just let it swipe across the detector. I can't imagine wanting a car in such an environment unless you frequently haul around stuff.
