They may well be the future but the marketplace will make this final decision.  Right now if you are wealthy enough and don't mind paying a premium for a status symbol the Tesla is a nice car.  What I object to is providing subsidies to the rich since they hardly need my help to buy their electric toys.  And, while I'm being grumpy, let this be fair warning that the next Telsa that backs out of their driveway without looking (you know who you are!) is going to get a walking stick through their back window (assuming I'm still standing . . .).
