His videos are good. I guess the only complication for driving in less covered areas is if something goes wrong at the first charge station, would you still have enough charge to just go one to the second? That is certainly one area where Tesla generally has us beat, at least for now.
In my limited 6 months with Chevy Bolt (the smaller battery), there were several short legs, but more than once something went wrong. The most annoying, but easiest to fix was an EVgo (one spot) down on one side of the highway, and having to go to the next exit, turn around, charge at the working EVgo on the wrong direction rest stop, then go to the next exit to get back on the highway in the correct direction, passing the first one on my way out again. So, some tens of lost miles, at night, tens of miles lost from that next leg.
It's been a very long time, I think in my small jet, it was something like enough fuel to get to the alternate airport, plus another 20% for possible delays. That can be pretty tough for an EV, especially in areas where L3 charge stations are few and far apart. Back up plan is L2 for enough charge to get to the next L3 station, but L2 can be very slow when traveling as opposed to when the car is in the garage overnight at home while sleeping.
