this' happened to me a bunch of times, except I wasn't going at 35 mph....usually going over bumps with a slack ass chain...and then I skidd it out to a stop. I was getting pretty comfortable with my chain derailing (using the quick exit plan of realizing chain locking up, and looking behind to swirve out of traffic) until it started coming off with me coasting away (chain jumping off the rear cog too).
