If you are fortunate enough to have someone in the car whom you are attracted to, this is really the best option. It's just unfortunate how rarely this is the case. We have found that often people we are attracted to are also people we don't terribly enjoy talking to. Hooking up in the car will allow you to kill two birds with one stone: you'll get some and you will have a sweet break from your lover's annoying perspective. We don't recommend hooking up in the car, if you're the only one in there: doing that in public is generally against the law.
