I'm going to repeat my advice I posted earlier... Learn to roll, and roll well. Yes, this works at high speeds. I was doing about 35 on my motorcycle when a car t-boned me. Rolled, and stood up. Sore for a year where the car hit me, but no injuries from flying through the air and hitting the pavement. 20 years of martial arts, but anyone can learn to roll. Practice so that it's natural and you don't have to think
