And that is something you would like to accept as a fair reason why someone in your family was ran over by a random teenager who found a driveable car standing around?
At least locals. In the news, I remember a story about drunk tourists finding a drivable electric golf-cart standing around. It's much less likely to run over a person than drive into the sea. Which they did. None was injured (by luck, that particular cliff wasn't high enough), the court forced them to pay for destroyed property.
