I think we ought to slowly get rid of all cars and create a light magnetic levitation rail system to replace autos altogether.
The investment to do this would be enormous, but the energy savings would more than pay for it.
We have more than enough rights of way to build these light rail systems, and I doubt they're cost much more per mile than building most roads.
Mag lev rail light rail systems can easily reach speeds of 200 - MPH and the whole thing can be run by computer.
You walk a block or two to your local station and transfer to intercity systems if your trip is longer than local.
We also ought to be creating pedestrian bike paths that give every person FREE passage from anyplace in America to any other place.
The cost of those people paths would be nominal, but I swear to God, if we built them, people WOULD use them, too. I can actually envision a whole way of life developing (for some Americans) based on not using (or using only minimally) those advanced transporation sytems I'm envisioning, too.
I'd ride bikes all the time if I had a SAFE PATH to take from place to place. AT 10 or 15 MPH even a trip of thirty or 40 miles is NBD
Seriously, instead of saving the AUTO INDUSTRY we really ought to be completely rethinking transportation in America entirely.
All transportation ought to be electric powered, 99% of the land transportation ought to be by rail including shipping material and people.
We ought to get rid of Jets' too.
They're incredibly wasteful, horribly polluting and they're not really all that much quicker, than serious modern light rail, either.
The FRENCH and Japanese have rails in service that do over 200 MPH in service now.
The USA can't do the same?
Sure it can.
And it should, too.
