She needs to slow down just for the fact that it could be any living thing, cat, dog, child, jogger...whatever that she plows down. I had a neighbor who liked to speed up our street like it was a drag strip. I am not sure what happened, but he has slowed it down a lot. I am thinking someone in the neighborhood called the police on him. Either that or he finally blew up the engine in his truck. He was very dangerous, not to just animals but everyone.
