I completed an 8 weeks, 10,500 miles round trip from Atlanta in my X90D. Listed are the places we stayed either because there were Tesla Superchargers in the town or the hotel had destination chargers. We stayed with friends and relatives some of the time, but mostly hotels. I have two issues. One, I could not drive from Canmore, AB to the Columbia Icefield with reasonable certainity I could complete the round trip (258 miles) driving at a reasonable speed limit. Two, I was not being able to drive the posted speed limit of 80 mph between Fort MacCleod, Alberta and Great Falls, MT (214 miles with lots of steep rolling hills in Montana). Three stations, Shelby, MT; Great Falls, MT; and Helena, MT have not been built yet. I started with 246 miles of charge (95%), drove 70 mph. Arriving in Great Falls with 22 miles or 8% battery remaining. I was able to drive the most of the route at 5 mph over the posted speed limit without having range anxiety. Finding charger availability was not a problem except LA area. I stopped every 2 or 3 hours (about every Supercharger) because our bladders couldn't last more than that, and averaged about 500 miles a day. I normally charge an extra 30 miles above what the route planner recommends to compensate for wind and elevation changes. Temperature was not a factor and had the AC on 95% of the time. All the stops were planned ahead of the trip so there were no big surprises. The route I drove includes the following cities:
Atlanta, GA/ West Monroe, LA/ Vernon, TX /Albuquerque, NM/Phoenix, AZ/Alhambra, CA/San Bruno, CA/Redding,CA/Redmond, OR/Bellvue, WA/Vancouver, BC/Revelstoke, BC/Canmore, AB/Great Falls, MT/Sheridan, WY/Loveland, CO/Granby,CO (no charger there, but there are in Estes Park and Silverthorne)/Wichita, KS/Mt. Vernon, IL/Atlanta, GA. I convinced the timeshare manager at Granby, CO to consider installing level 2 chargers. I used a 110VAC there overnight to get 3 mph charge overnight to gain some additional mileage before reaching the supercharger in Silverthorne. I took one route over Loveland Pass just for the experience.
The Auto Pilot on auto steer help kept us safe as I occasionally dozed off for several seconds after lunch toward the second hour. At which point, I had my wife drive so I could nap until my next turn to drive. I normally drive with Navigate on Autopilot, but with Lane Change Confirmation-Yes. I don't like the No Lane Change Confirmation because sometimes it waits too late before passing a slower car and I am stuck behind the slower car until the line of faster cars completely passes. Other times it takes too long before it moves out of the passing lane and I am holding up traffic behind me. I rather be in control when to make lane change.
