ha!! my friend tony has taken this to a whole new level. after not having driven in months he had to car-sit. but he found that his navigation was still very bike-oriented and sometimes he would forget completely that he was in a car: ie. not heeding which direction traffic goes, jumping up onto curbs to avoid potholes (which he would have done on his bike normally) and the funniest of them all -- looking BOTH ways when at an intersection.
