I actually don't know if it was that exact one, but it heavily featured a Lamborghini Countach and butts. And I don't know if it's readily apparent to people who aren't experts in dissecting symbolic imagery, but that poster subtly suggests a connection between automobiles and sex. So at age 16 I knew only one thing: If you didn't have a car, no woman would ever touch your dick. Where I was from, that was both the age at which you could get a driver's license and the age at which you could legally hold a part-time job. The only reason to get a job was to get your own car, and it sure as hell wasn't so I could help Mom with the grocery shopping.
And even though there are presumably an equal number of male and female drivers in America, car culture -- the love of cars, and the worshiping of them -- was always about manliness. Race car drivers are male, mechanics are male, and car ads portray females as merely one of the accessories that come with a nice one. I don't know exactly why our means of transportation was always seen as a male-dominated thing (it was the same when we were getting around on horses, right?), but it's so ingrained that we don't even question it.

But Soon ...
It would have been unthinkable when I was a teen, but the hot new trend among kids these days is to not bother getting a driver's license at all. Back in my day, around 90 percent of 18-year-olds had a driver's license; now it's down to 70 percent and falling rapidly. There's a bunch of reasons for this, part of which is simply that more people live in cities now, where life is actually more difficult with a flame-painted El Camino than without one. But these are just the early rumblings before the collapse.
