I rode bicycles a lot. Certainly when riding bicycles one must have split second and correctly made decisions. My driver training involved simulated head on collisions where an instructor would get in another car and drive at me head on to train my response. So I had reasonable training. It was just that in a parking lot I never expected someone to just throw it in reverse and back into me without looking where they were going. It simply had never occurred to me that it could happen. So when it did happen I was so busy thinking about what I could do that I didn't do any of the things I could do (honk, or put it in reverse and back out of the way.) Since then I've avoided dozens of accidents that were new and unique in their own way, but also I've been through a few situations and have now developed good instincts about what the options are in a given situation. It's not unusual, by the way. Pilots train emergency scenarios for just this reason.
