There has been talk about battery swapping as a way to quickly 'refuel' on a trip. Tesla at this point is not going in that direction and no Tesla owners would consider dropping off their own new expensive battery for a used rental. I understand that. But what if we were able to have the best of both worlds?
I read in these forums about how much cargo space the "S" will have, so what if Tesla made a 'rental battery' available for us to use anytime we needed more range than the battery we picked for our car affords us. Think of external gas tanks on a fighter jet. Pilots use them to augment their distance, but when empty they switch over to their internal tanks. Maybe that analogy isn't great but, we can do something similar. If Tesla designed a rental battery which could be configured to fit in either the front or rear trunk, and assuming the hookup could be done easily, maybe we could add another 50, 100 or more mile range to our 'internal' battery. And if there were different swap out stations along our route, that would be much quicker than even waiting for a 'quick' charge. Yes, it would add another 500 or more pounds to the weight of the car, but heck, we have a lot of cargo room, right? It might not all be used for luggage. That might just be the compromise we need to give us complete freedom on the road. Your thoughts?
