While many bike races don't start with sprints...I'm fairly certain that sprints almost always start with sprints?
Unless you had some rule about trying to appear casual and nonchalant on the start, maybe you could introduce a rule that required all racers to lean against a brick wall in a leather jacket, smoking a cigarette, one leg up all James Dean lookin, then stub out the cigarette, swing a leg over the bike and casually pull away, building up speed while controlling your breathing so as to maintain an unconcerned visage...
Or accept that there is an inherent risk in any competitive cycling event & that this is highlighted by the occasional mistake....
Hell, I once came off a "ski jump" style hill arrangement on a Norba course in louisiana. I didn't get to pre-ride cause of the long drive, I had no idea there was a 30 foot drop that rolled into a short vertical wall, right around the corner from a fast bit. I hit the turn hard and dropped into space, rolled into the base, hit the wall without pulling back, was flying through the air rear wheel where my head should have been, landed on the front wheel and managed to ignore the urge to brake, rode on the front wheel for 15 yards and eventually kicked the back wheel down, and continued on.
There were spectators all over that area cause of the jump formation there, first I got "Ooooooh" as in, "he's gonna die" but when I pulled it out of my butt and landed it I got cheers as in "look! he didn't die!".
I gave it a proper go on the second lap...not nearly so much cheering...they were there to see the spills
There is risk in racing, don't like risk, don't race, don't like being subjected to risk by others due to the -possibility- of a mishap, don't race and don't attend races.
**** happens?
to be honest I don't understand the argument here, what are you guys arguing about?
