Unless those 5% of rides start an airplane flight away, I can't imagine very many people are going to pay all the costs to own a car and all the costs and hassle/time-wastage of renting a car once or twice a month. They'll buy a PHEV, hybrid, or conventional car and wait for the BEVs to improve. (I'm a LEAF owner, but can trade cars with my spouse when I need to. I think twice in 7 years we've both needed to drive a distance in a single day where the shorter drive would stress the LEAF.)
