The world is full of idiots.Why assume none of them will be behind the wheel? I don't care who is right. I care who is alive, namely, me. My dad taught me defensive driving and I am eternally grateful to him for it. Defensive driving means constantly anticipating what can go wrong and being prepared for it. I think the truck driver was a dick but I would have been slowing down anyway. If he wants to cut me off that badly, he can have it. Karma will take care of him.
