You haven’t thought this through very well have you?
Prior to WW II this country was primarily an agricultural nation with maybe 20% of the population living in cities. Most of the population worked at home or walked to work.
Today more than 80% of the population lives in cities and the vast majority of the population commutes to work with the vast majority of the commuters driving their personal car to and from work.
If as you say we were to totally ban the importation of oil on a single day and deal with the consequences This country would go from being the economic power house of the world to being a third world basket case with food riots and people starving in the streets.
I’ll deal with the terrorist thank you very much if your solution is the only other option (which it is not).
Better than you have it seems. Neighborhood work sites could be implemented very quickly and they could easily get rid of half or more of the commuting.
In too many parts of America today God could come down out of the sky and give us all the gasoline we need for the rest of our lives for free and it wouldn't fix the problem; there'd still be people spending three to five hours driving to and from work in crawling traffic every day.
Henry Ford said that the car was there to allow the city fellow to go out on picnics on Sundays and the farmer to gt into town to shop on Saturdays. We've come a long and dangerous way from that simple vision to our present misuse of technologies.
Again, we have more untouched oil than the rest of the world put together, particularly offshore of Fla. and Cal. and under the Rockies in Utah and Colorado before you even start to talk about shale, and if anything we should be exporting the stuff and not importing it.
