it is not necessary to ban them, that, to me, is not the correct way to look at it
A vehicle is actually just a fuel tank, constantly searching for more fuel, while transporting humans
witness the east coast fuel shortages simply caused because the owners of the fuel pipeline could not trust buyers to pay for what they got.
It was shut down mostly because they didn’t trust buyers to pay costs, and 10’s of 1,000’s of vehicles ran out of fuel, as did the stations that supplied them.

If there are virtually no fossil fuel stations to supply unobtainable “go juice”, bans on fossil fuel vehicles won’t matter,
it will be a moot point,
they will become variations on “yard art”, slowly rusting into piles of reddish dust like the 2 on our farm did over 4 decades, trees and brush growing up through
