3. They can dump 150 miles of drive time into your car in an hour Which works out to what, one hour of idling at the station for every two hours of driving, making your trip roughly 50% longer compared to a gasoline car? We need much better batteries and/or better charging technology for this to become attractive. Graphene-based batteries are a promising candidate: https://vimeo.com/51873011 https://vimeo.com/51873011 (For the record, I think Tesla and their Supercharging stations are awesome, just wondering why the author would list this ridiculously long stay at the charging station as a "mind blowing" feature.) (And yes, battery swapping instead of recharging would also solve the problem.)
