Re: Why terrifying?
"Being able to drive until almost flat, pull up to a station and just move your stuff to a new car that had been dispatched to meet you solves quite a few problems."
Who cleans up after the sprog puking in the back seat, and the dawgs puking and/or peeing all over the rest of the interior? Or does that just get passed on to the next poor schmuck? Obviously smokers will become second-class citizens, getting older, well-used replacements ... nobody but a smoker would want a car that had been smoked in.
And of course we all know how people treat rental cars ... would YOU trust your nearest & dearest to a vehicle that had probably been bounced off of most of the inanimate objects in three States? I certainly wouldn't.
