215 mile range (assuming without A/C running or anything else to make it a pleasant trip) is actually pretty decent, certainly usable...
Even using one of Tesla's "supercharger" stations (if you can find one while traveling - ha!), you are looking at a half hour twiddling your thumbs between trip legs.
Our use case is probably not typical, but...
Most of our trips are to nearby towns, usually no more than about 40 miles away. But we also make regular trips to Knoxville to see family and for "big city" shopping. It's roughly 100 miles each way, and over mountains each way, so I imagine range suffers there. Plus we need to do some driving around while we're there. But...
30 minutes at the Supercharger nearby in Turkey Creek would be a trivial delay. Time to stretch, get coffee or a meal, get caught up online, walk the dog(s), that sort of thing.
So, it would just about fit 95% of the driving we do. We'd keep our Flex for towing our travel trailer and longer trips where the Supercharger grid is not handy.
That said, I resisted putting down a deposit. I don't like buying ver 1.0 of anything, and who knows what the options will be by the end of next year? I keep thinking our ideal everyday car would be a plug-in hybrid, where in a pinch a small gas engine could recharge our batteries as we drove. Such things exist, but right now the electric-only range is woefully low.
Right now the goal is to nurse our 2005 Honda Element with 180,000 miles as long as possible, which will only expand the options!
