There was another poster in another thread who I ended up in a debate with because he thought I was saying that falling over on a bike was normal (I wasn't intending to say that). He was saying how nuts it was that some people were trying to push falling over on your bike as "normal" when clearly it's dangerous - smashing into concrete or asphalt is always hazardous. He was totally right...and I was a bit embarrassed that my post could be read that way.

Things are riskier in pro sports no matter what the sport, tour de france riders are taking bigger risks than your average person riding a bike is. But in average riding one shouldn't be falling over pretty much ever. Biking would be a lot more dangerous if it was common and inevitable.
