Wait til you have to go into the left lane on a 55 mph road to pass a car.
THAT is a rush.....especially when you realize you just passed a State Cop in an unmarked car....on your bicycle.
(I have a 4 lane that I need to occasionally ride that has a bike route on a wide shoulder and a long downhill, and it was blocked by a breakdown. I had to merge into the traffic lane and I was actually moving faster than the traffic because of the downhill, and being all tucked and aerodynamic down on my aerobars.)
