It's really not a problem running over one in corners as long as you keep your cool. Just don't try to correct suddenly. The snake will only roll a little bit and you'll be on your way. Problem is people hit the panic button and try to correct for something that doesn't need correcting. That is unless you are riding with a very light grip. Then you might get the bar jerked out of your hands. With traffic now I ride with such a tight grip that I have to tell myself to relax.
