I thought this was the result of front wheel drive.

  Rear wheel drive cars also do it. The caster on a car mimics that of the wheel of a shopping cart. Having the pivot axis be at a slight angle relative to the direction your travelling makes the wheels trail behind that axis. It does tend to be more apparent in front wheel drive cars, perhaps it's the weight of the motor? It's really important to get right in motorsport, as it denotes the characteristics of the car when you've oversteered. A car with correctly set caster will "self steer" itself back to straight without any driver input, and it will guide the car while oversteered in a way that's balanced with the direction the car's actually heading rather than where it's pointing (if you're intending to be sideways, like in drifting).
