jedi – im not sure about that in BMX, a few friends shoot for various bmx publications and it has never been mentioned or been a consideration on shoots. Also have plenty of friends that are regularly publicized, a helmet reducing money has never come into it.
As for the OP, they accept the risks, what’s wrong with something if you accept the risks? It would be like not MTBing because it can be potentially dangerous.
Part of what makes BMX great is how relaxed an attitude toward it is. You don’t need to think about it, you don’t have to prep for it, you just get on your bike and go. Whether it be middle of the night or the middle of winter, you don’t need a good location, or have to go far, flat tarmac will do, if you want to ride, you just pick up your bike and go, no restrictions. Not having to prep with safety equipment or clothing, bike cleaning or gear fettling. It just adds to the lack of restrictions it has.
