THAT PROFESSOR IS WRONG.

People, especially american men, Love their automobiles, and will never give them up. How many motorheads does this country have? 100 million? 200 mill? people who spend all their spare time rebuilding and restoring muscle cars, making rat rods, street modified's. The obsession's with motor sports like Nascar, or car chases on the big screen, or the whole street Tunner scene are all evidence of this.

the only way people will give up their cars is if they are made illegal to own or drive.

That will not happen, ever.
