You think that he's probably faked it but you never know it can happen in real life. So better safe than sorry.
* One of my fathers driving lessons to me was that you never drive through a pile of leaves. There could be a rake that someone forgot and it will puncture your tire. But there can also be an animal or a child hiding. Never drive through the leaves like that.
* There was 2 kids that did this to surprise there father when He came home from work...he killed them. Whether its a true story or not....its never safe to do this...unless supervised as a child in the yard. But I will never do this and will teach kids I know not to do this either along with my own. Just the thought of that being true makes me ill.
*Even if it's fake, there's a reason you should always think before you act... Why put the pile of leaves in the driveway in the first place when you could have just as easily put it a few feet away?
