Jason, that is an excellent point and one that I think has been somewhat overlooked in the world of new-rider training. I suspect that part of the reason it isn't mentioned is that to mention it would require to explain it, and to explain it would really require an exercise for them to do in order to understand it properly, and suddenly, we've got another 30-45 minutes of class time to add on to an already overloaded amount of time.
No, we do not deliberately feed misinformation. We will never ever ever say, "You NEVER brake in a turn." If we make a qualifier like that, it will be "You will NEVER brake in a turn while in this class". Students may extrapolate that what's true for the class is true for the street, for always, and that may be a an side-effect.
But unfortunately, we don't have time to properly discuss the all the differences between "in here" and "out there" and "these basic skills you're learning now" and "those advanced skills that you may, and hopefully will, end up becomming familiar with and applying properly, later."
And finally, let's all be honest with ourselves. Have you EVER had to use trail braking when you were out riding in a manner that adhered to the laws of the road like following the speed limits (even the orange ones posted at the entrance of turns ) and using the 2-second MINIMUM following distance. If you did was it a rare exception, or the rule? [/B]
