Edit: The Electric Road Trip blog is now live. I'll place 99% of my communications there. Check it out at: www.thelectricroadtrip.com I chose to buy a new 70D instead of pursuing the method described below. OK, I've been watching the superchargers multiply like rabbits on the mainland and I'm getting itchy for a mainland road trip. If I could take a year off from work and just travel (visit friends, ski, hike, explore, sightsee, etc.) wouldn't it be cool to do so in a Tesla in another year or so when the supercharger network is solid? Here's a rough estimate of costs as I see it: $ 2500 (ship Tesla S to and from mainland) 2500 Install supercharger option in Model S 10000 Upgrade 40kwh battery to 60 kwh battery through software upgrade so that I can use supercharger $15,000 Auto cost Yikes! Ok, this plan probably only makes sense if someone already has a car with at least 60kwh of battery or plans to upgrade anyway. Plan B would be to buy a supercharger-equipped Tesla on the mainland, drive it a year, and then sell it. This solution might make the most sense for me. The negative is that I would own two Teslas that are both depreciating that year. Has anyone considered such a road trip, and if so, what insights might you offer?
