Again, not to be a huge asshole, but if you lost control of the bike… then you didnt use proper technique (crashing is not standard practice in any of the MSF courses). Side note, if the bike went down, and you didnt make contact with the car, then my guess is you didnt use the brakes to their full capability. Meaning a bike sliding on its side could/should have stopped sooner had the tires been in contact with the ground and brakes been applied fully.
Not saying you’re at fault. Id be upset if I dropped my bike as the result of another driver, but panic sets in, people freak out, and basics are forgotten. I strongly suggest the practicing to ANYBODY who rides, I still do this on a regular basis, as its never bad practice to sharpen your skills.
