It is surprising how lightly a bike can get away after hitting cars on occasions. We had a car pull out on us when we were on the tandem once. We hit the front bumper hard and the driver apoligised. Problem was the car hit the wrong tandem. Our front wheel is a Full Downhill spec one and wiped out the flimsy "Plastic" bumper.
And yet on other occasions- Just a touch and a bike can be written off.
