Changes since congestion pricing started in New York

As a long time NYC resident who moved out during Covid but commute to work in the city. I definitely noticed less traffic on the streets and less noise.

I see a lot of talk of other cities that don't have good public transportation. For example, between Flushing in Queens to 8th Ave in Brooklyn, there are privately run buses at affordable rate and get you there at half the time of trains. There are buses from a lot of residential areas in NJ that are closer to NYC that go to port authority (west side, 42nd st) very quickly. In fact, those buses are getting there faster and more comfortable than ever due to congestion pricing.

I'm curious, do other larger cities where commercial is concentrated into one area not have a private mini-bus(es)? I know public transportation would be great, but having a competitive environment for privately own bus services might be the answer to a lot of cities.

In Ho Chi Minh City (and probably Vietnam in general but not 100% sure). Our commercial district is very concentrated.

The busses in general are some form of public-private partnership. Several private bus companies operate the city busses. There are some annoying edge cases. For example, pre-purchased tickets are a mess -- better pay cash. If another operator takes over your route, even temporarily, your tickets can't be used.

Mostly it seems to work though, I take the bus fairly regularly and it's quite nice. It's clean, has OK air conditioning, and arrives frequently enough that I don't have to check the schedule. There's someone to help elderly people and children on and off the bus. Elderly people ride free, reduced price for students, etc. It's pleasant.

Some of these busses are mini-versions for less popular routes. I think I've even seen a couple of other vehicle types, like some form of van (rarely). One or twice a sort of truck with benches.
