The track isn't a free ticket to never crash again, it's true. But if you ride within your limits, respect your bike and the riders around you, crashes are not a common occurance, and when they are they tend to be very minor. It's not the crash that kills, typically, it's the sudden stop into a house, a tree, a curb, or a car that does. You'll see a bad one every couple of trackdays, but for the most part, they're not that bad. The other thing is: Fr0ng aside, there's almost no chance of someone not finding you when you crash, medical care is on hand, and deaths are freak accidents, not a significant % of overall accidents, like they are on the street.
Honestly, I think that at this point in my life, riding is in my blood, and the day I give it up will be the day that I give a part of myself up. Maybe I'll find another passion to fill my life, maybe I'll let the page close peacefully...but I don't plan on doing that until i've scribbled every margin I can find. :laughing
