Obviously there are people who have decided to ride on the street, there are people who have decided to ride on a track, and there are people who do both. The original post was asking for help with riding technique, something that will do more for a rider than any gear or aftermarket part. By simply getting on a soapbox and condeming them for not taking your view is not going to benefit this person. I applaud the folks who gave real advice because learning to ride better could ultimately save that persons life. To act as if riding a bike anywhere but a track is an act of suicide simply puts you in line with the ignorant masses who see us all as eventual road splatters. I doubt that anyone is promoting riding on the road at the limits of your bike, or more importantly at the limits of your riding skill. But there are very responsible and relatively safe ways to improve your skills and get a little excitement while riding the streets. Learn your limits, know your limits and ride within your limits whether on a street or a track.
