And make those buses have dedicated lanes cars can't use. It is amazing how nice a bus can be when it's not stuck in the same shitty traffic as all the cars.

Exactly - this tactic converts busses from "shitty cars that stop all the time" to "faster, huge cars with a built-in chauffeur."

I am speaking more to the political possibility. Things like increasing car parking costs, removing car parking, and spending money on more frequent buses is feasible, but politically impossible.

Sufficient voters will have sufficient resources to own and store their own car, and they are going to want to use it, and they are not going to want to spend money on empty buses.

One of the most important factors in whether someone will vote for a transit tax if is they can imagine riding it themself. Since the current system sucks people can't imagine that and they vote no. Which keeps these networks starved of resources.

Meanwhile legislators approve billions for highways every year. Zoning laws and minimum parking laws are kept in place. Every time gasoline prices increase politicians seek to sooth voters/motorists.
