Public transportation varies widely in the US. A few places have great subways and commuter rail, but most don't. A few places have reliable bus service that has enough capacity utilization to actually save pollution and money, but in a lot of cases bus service is supported only as a means of getting low wage workers to their jobs. In many many places on-demand rides are the only plausible thing that would reduce private car trips.
