Not for a long time.
I've been doored, knackered the rear derailleur;
Over a car bonnet when the car took me out on a roundabout, buckled the back wheel;
Hit by a car who reversed onto the road and then drove straight into me (not on purpose (I hope!)), I stayed upright but they bent the seat stays and wrote the bike off.
Not so much as a scratch on me on all three, the dooring was the scary one as I slid down the road just waiting for a car to go over me, thankfully nothing did.
I've had a few offs not involving cars. Hit tree roots coming through the path which resulted in having my elbow stitched up, which I was surprised at as I thought it was a scratch, luckily our lass insisted I went to A&E.
I know someone who hit a gate across the road, I thought he was dead, he got up with a cut on his head and his bike was fine.
@13 rider might remember the details more clearly than me
