Hmmmmmmmm.......... that's better than the present situation.
The odds that this does not stay in responsible hands means that it is a VERY BAD idea. Before cell phones became cheap, every man I knew who was a father of a college girl was signed up for one if the girl had a long commute. They all had stories of empty cars found on the roadside. Some were probably apocryphal, but it does happen. Having the bad guys being able to pick & choose which cars would 'fail' in the middle of nowhere is not a good idea.
