Both are dangerous, someone is going to get hurt or killed.
"Both are dangerous" On that we agree.
"Someone is going to get hurt or killed" If you change the "is" to "may" I would agree with that statement as well. As you stated it is just plain silly. You have no way of knowing if that is going to happen. No different than guns, or knives, or driving to work. Any could happen, none are certain to happen. Silly statement.
Just to be clear, I am not condoning street racing or street drifting.
