You're right we can't see or predict everything. I just heard a story where a pilot had to drop a snake out of their small private aircraft while flying over a highway. There was a high likelihood that a driver below had no way of knowing a snake might fall out the sky and perhaps shatter their windshield. Most things that happen on the road though aren't that random. I once had a bicyclist coming down a curvy mountain road. There was something about their riding that seemed uncomfortable, so I started slowing down. The biker then wiped out and crossed over the yellow line, stopping a few feet from my truck. If I hadn't been proactively scanning and thinking about everything that could go wrong they probably wouldn't have been able to get up, and say "thanks for not running me over." I don't write this to judge you, or brag about myself. I've made plenty of mistakes myself. This is more a general lesson for people: synthesize all inputs received while driving and take proactive steps to mitigate potential risks.
