I wouldn’t use public transport. People have generally chosen to use cars, and doing so makes sense for the development type.

If you definitely wanted to take the public transit route, busses are probably the most well-suited thing that could be deployed tomorrow.

The best near-future public-transit thing is probably a fleet of self-driving cars; that’s well adapted to low-density housing, permits for transit to doorstep, and permits for a higher usage ratio than individually-owned vehicles.
