This is one of those positions that's a little meh in the bedroom, but it's actually the most efficient use of space in the car. Just sit like you're a passenger facing forward and have your partner position themselves on your lap with their legs stretched out across the backseat. Bingo, it's like the guy who invented the four-door car did so with this exact scenario in mind. If you're uninhibited enough to exchange bodily fluids in a filthy cab, this is also a perfect "your place or mine?" substitute.
