And then it becomes an arms race; you see the highway full of large SUVs, and you feel vulnerable in a tiny compact car, because you think they will crush you in a collision, so others start buying SUVs to &amp;quot;protect&amp;quot; themselves. These land-beasts might be comfortable but they are unsafe, take an excess and unfair amount of space on the road, consume too much fuel, and trigger arms race. They need to be regulated to death for most users.</text></comment>

Police verified that she wasn&amp;#x27;t moving faster because she practically flipped it in place, rather than ending up a significant distance away. Just a case of hitting at just the right angle and riding it up, I guess.</text></comment>
