I'm betting you will probably find more of a correlation between the ages of people and their sexual practices in cars. Mostly that the younger you are, the more likely you are to have sex in a vehicle.

May be interesting though to see if the amount of sex in cars increases the older you get depending upon what color of car you drive. Maybe a bit of, "mid-life crisis, I need to get laid in my hot red sportscar," kind of sex.
