That's ridiculous. My trip was from Ottawa Canada to Saskatoon. It goes through some seriously unpopulated territory, unlike yours. It does follow major highways, so there are Tesla superchargers along the route every 100-150 km or so. We'd stay at a hotel with charging overnight so start at 100%, drive for 2.5 hours and then bathroom/charge for 15-20 mins, drive another 2.5 and eat/charge for 40 or so, repeat the morning pattern in the afternoon, and then drive for another couple after supper before stopping at a hotel to charge while sleeping.
