As a truck driver myself I am always SO afraid that I'm going to hurt someone else on the roads. I've been a driver for the last 14 years of my life, I've been to many safety schools and taken so many lessons on how to do my job to the best of my abilities, but you NEVER know what others are going to do. I don't know if I could continue driving knowing that I had killed someone, regardless of whether it was my fault or not. I'm not saying that I drive like a grandma, far from it, but I always do my best to be safe.That first video, I understand that his truck was probably totalled, but think of it like this; he probably saved at least a few lives by inadvertently "sacrificing" his own truck like that. He didn't mean to do it like that, he was just trying to avoid the crash, but it just so happened that he stopped that trailer from smashing straight into a much smaller vehicle and possibly causing very serious harm to those people or worse. Accidental hero, I say.
