I tipped over 3X when switching to clipless pedals (lesson: grin and bear, its worth it). Slid out on ice last year (lesson: the verge of the path is more likely to be damp/icy). Close call with being doored last year (lesson: look into the parked cars for heads) and another with a near right hook (lesson: don't enter intersection with a car to your immediate left, if you do then cover the brake and be ready to turn hard). Fell at low speed due to a loose stem on a newly assembled bike (lesson: double check tightness of all key fasteners before putting the bike into service).

Otherwise, I can't recall crashing on the road (as distinguished from in the dirt) in years. Actually, not in decades. Not living in the snowbelt helps, but if you are not racing, there is no particular reason why crashing should be a regular or even semi-regular occurrence. Sensible, defensive motorcycle riders go decades, even lifetimes, without dropping their bikes. Bicycle riders can too.
