I was around then, and much earlier. The talk of running out of oil gave it 100 to 200 years when I was in school in the 70s. While the number of cars is up from that time period, the amount of gas used has gone down thanks to fuel efficiency. I drive a gas guzzler, but I can still get by on a tank of gas a month, with plenty left over using it for my personal needs. I rarely drive more than a few miles from home and when I do, I make multiple stops for the various things I have to do. If I don't have to leave the house, or can walk it, I do. Otherwise, my car can sit for days without moving. Others are getting on the band wagon.
But that's me.
