Another question related to my upcoming trip: Does the navigation take into account the effect of mountains on range when deciding if you can make it to the next supercharger? And will it tell you if you try to program a trip that you won't have enough range for? I will be taking a route I've never taken before. Instead of driving the stinker direct from Spokane, WA to Revelstoke, BC, I'll be driving from Spokane to Kelowna, BC, to hit the supercharger, and then on to Revi. The direct route is 305 miles (I'd have happily paid an extra $20K to have a 350-mile range) and 305 miles is cutting it too close. Any unforeseen problems would leave me stranded. Spokane to Kelowna is 243 miles, which should leave me with 65-ish miles of buffer, except that I don't know what the terrain is like. And you don't recover in downhill regen all the energy you lost on the uphill. None of the other legs of my trip will be a problem. Revelstoke to Golden has a very high mountain pass, but it's only 92 miles, with superchargers at both ends. Only Spokane to Kelowna and back are the worrisome legs. There's no charging opportunities other than an RV park along the way, where I could beg them to let me plug in to 240 v. 40 a. Yes, I am a worrier. I don't like travel, I don't like long drives. I do this trip because it takes me to my favorite places to do my favorite activity. (Hiking in BC.) And I HATE gasoline, so I'm really looking forward to not using any on this trip.
