If you had teenage/young adult years as my own, you might have had the unfortunate experience of trying to make an intimate experience work in a car. If you haven't, just watch any episode of Cheaters like, ever.
It's tough work. Unless you have the flexibility and the hip width of a professional ballerina or have the luxury of rolling around in a limousine every day of your life, working around the awkward layout and small nature of a car in order to facilitate some heavy petting or more, can be difficult.
You have bucket seats which are not conductive to fitting too normal sized humans on. The gear shift an emergency brake which can be a nasty surprise in the behind if you aren't careful. The roof of the car which can restrict movement to mostly rolling around, no thrusting.
I don't know. I'm not a fan.
Some people are. Some people like the immediacy and expediency of it. "Gotta-get-it-now-or-never" kind of attitude. (Please see the earlier reference to teenagers.) There's the "in-public-but-not-really-in-public" nature which can be nice for some "safe" voyeurism play. (Just be careful for where you park and don't get caught. It's technically still lewd conduct in some states.)
