It’s not that easy. Sprawl needs to be addressed. Our cities are build around cars. You can’t slap a few busses in a town expect shit to work.
I work an hour away from my home. I would take a train but there isnt one that is reliable or cheaper than driving.
Having a light rail system that connected the east coast would take centuries unless the government acted with unprecedented action and speed even then it would be decades.
I’d love more public transportation yes.
I am saying right off the bat I think biodiesel would be a more viable alternativ as it could be relatively easily adopted as the infrastructure is already in place.
Edit - I was probably a bit verbose when I wrote this. Clearly it won’t take centuries. Decade or two at the most
Edit two: I was also misinformed about biodiesel - thanks for the helpful information, I appreciate it.
