We should invest more in public transit, but there is literally 100 years of built infrastructure which has fueled patterns of development which make taking transport unattractive. So we can invest more, just dont expect it to result in many fewer cars.

More bus lanes would be a cheap and easy start. The problem with current car centered cities is that taking transit is slower than taking a car so people with the means use the fastest transit option by driving. If you remove minimum parking laws and increase bus lanes which let transit users bypass traffic, this is a low cost way to encourage more transit usage.
