I wonder what the most efficient speed is during a road trip when you only have AC charging available. No point going superfast if you just have to then charge for longer. I guess for the Model 3 with a 40ah charger this means a maximum charge rate of 9.6kw. Driving at 110kmh/70mph we are using about 18kw/hour in a Model 3 so clearly this is way too fast. at 90kmh/55mph this seems to be around 12kw/hour judging from one of bjorns video so somewhere between 80 and 85kmh is probably optimal?
