You can get an EV right now and if you have a house in the country side, you can power it almost exclusively using solar power. That would be fusion power from the big fusion reactor in the sky. We've had fission power for about 80 years already.

I actually called out public transport as part of the solution. Autonomous driving makes small buses for uneconomical, remote destinations more feasible. Even just a shuttle to a commuter rail way station would be helpful. The challenge is that these remote areas are depopulating because you can't easily get there. Public transport is amazing but not when it means waiting for a bus for 2 hours that may be delayed by another hour or be cancelled entirely. One plus side of the countryside: not a whole lot of traffic jams there.
