You are correct. But in "flexibility/practicality", I'd also note that I do road trips maybe 5-10 days a year, max. The other 355+ days I'm driving around Miami and the surrounding areas, and even on a VERY long driving day I don't get over 120 miles... and the P85 can do that with its eyes shut, A/C on full blast, stupid-fast acceleration at every light, and so on. So the flexibility is that I can always go anywhere I want in my daily life, without ever having to stop and think about whether I need gas... because I never do. No more stops at gas stations in the middle of the night on the way home, no more filling up in the rain, or standing outside in 95F and 95% humidity while filling up. No more fumes, no more hunting around for the best price, no more worries about whether X or Y gas station is maybe doctoring their fuel a bit to pad their margins... none of that.
IMHO flexibility/practicality favors the P85 those 355 days of the year: about 97% of the time. Yes, I have to put up with some inconvenience and more time spent planning and charging the last 3% of the time. I'll take that tradeoff every time and twice on Sunday, please.
