Strikes me at least that the projections for massive growth of ride sharing are wildly optimistic.  Unless you pay for the astronomical cost of the Cadillac ride sharing progream, you are likely to be stuck with an undesirable car (sorry only the ugly electric BMW is available right now) that has been abused by the previous occupant (spilled pop and ice cream, grafitti, rips from transporting IKEA furniture....).  If you find out your child forgot one of their skates a few minutes after you wave goodbye to the shared car, you're in trouble.  The Ford F-150 is the biggest selling vehicle and most have a selection of key tools and equipment locked inside that owners want to have handy.  It is expensive to own a car or truck but it is usually money well spent.
