I always took it to be literal, that he’s talking about if they go out he wants to be the one to drive the car.

And it’s a great indicator of just how up his own ass J is.

He thinks he’s about to connect with this woman, and have a fling, maybe more, but in that moment what’s important is that he assert his macho persona that he is the Man and he drives because That’s What Men Do and to be driven around by a woman would be emasculating.

Also, Linda Fiortentino is really fuckin hot.
