Depends on the 'bent. On my LWB -- a Tour Easy from Easyracers -- my eyes are level with or slightly above those of a driver in a normal-sized auto. (Whereas on a diamond-frame, I would be 30 cm or so above the driver's eye level.)
If I were riding a low-racer, on the other hand, I suppose I would need prehensile eyestalks if I wanted to look a driver levelly in the eye.
