Sounds to me like people just get to dam close. I drive it like a normal car. I am not going to cover the pipes, wait for the to cool or put any stickers outside of the car. If you get burned, you are to dam close!! Don't like to see it happen to little kids, but in my opinion it is the parents fault in that case.
As for getting bit by the dog, I would have only expected them to pay the medical only, as I would have had to pay for the owners after I punched them!!
