Nah just normal driving, although those other types may be fun now you mention it. I just love being behind the wheel, the sense of control, the speed (sometimes, lol). Especially if it's a good car and it just glides over the road. I love running too, I guess it's kind of similar. And driving at night down a country freeway is one of the most serene experiences I can think of. I like having a car too because there's a sense of freedom, you can escape the world at any time. It's a bit of a common theme in pop songs, you know, get in the car and drive away (Pearl Jam Untitled a good one, or Missy Higgins Steer), there's a certain freedom but control at the same time.
Heaps of things I love about it I guess. Maybe it's a guy thing - you don't get the same thrill?
