Nope, no kidding.

Each of us has our own life experiences to rely on. Get threatened with being run over or off the road a couple times, and it might change any person's perspective.

Note that I didn't escalate the situation, merely prepared for the worst. After all, we do need to be a bit sensible about these things. Besides, I doubt if he or anyone else saw my gesture. More for my benefit and closure on the situation.
