Bikes, feet, maglev trains, - stuff like that.
IMPOSSIBLE…Unless the US becomes just ONE BIG CITY with no suburban areas. It’s IMPOSSIBLE for me to take any mass transit on a regular basis. Real tough to walk or bike 45 miles to work…ESPECIALLY IN SNOW.
As for the future…It’s very tough to say. I don’t envision the personal transport vehicle ever going away. I think electric vehicles that have a range of 200 miles and can recharge in minutes is within my lifetime. Hydrogen vehicles are also within my lifetime. But for the near future we’ll still have the internal combustion engine. The source for the fuel is the question. Diesel from Coal is very very doable right now.
