My Model 3 is scheduled for delivery next week and planning a road trip (Minnesota to Massachusetts) this fall. I've been playing with 3 trip planners (Tesla online, A Better Route Planner, EV Trip Planner). All 3 appear to me to have you make unnecessary stops; i.e. stopping at a supercharger when the next supercharger is within range without a stop. Where details are provided, these trip planners have me charging to 7x%. I realize that charge rate slows down past 80% charge, but there is significant overhead in visiting a supercharger (off freeway, on freeway). For my planning (as a complete novice), I was assuming charging to 95% and not going below 20%. Is this not wise? For local travel, I'm planning to charge to 80% and not go below 20%. Any other thoughts on road trip "best practice" are welcome.
