You are still going to have to reconfigure highways for bus lanes and build bus terminals for a bus service that is even remotely competitive with driving. And then, you are going to have to get over the social stigma against riding buses, which is going to take a generation to fully remove.
Cause we already have all the bus infrastructure (roads). Stops are pretty easy to build. I'm not talking about theoretical benefits.

Also roads need to be fully rebuilt about every 10 years so on the time scale these things take to change anyway we’ll have to rebuild it all anyway
