>Public transit has failed to solve the problem despite a 100-year head start.

I take objection to this because, aside from other cities where public transit is the norm, the interurban system in LA [0] was dismantled, partially because it was forced out by cars that increased congestion to the point that streetcars could no longer run on time, and partially because of car companies advocating that buses could replace the streetcars (they didn't).

Things don't exist in a vacuum, and LA decided to make itself a city where you could only be comfortable getting from place to place inside a car.
