I can totally relate to the range anxiety. I rarely do long trips at the moment but on a 70-mile journey back home I was diverted off the highway due to roadworks, it was quite a diversion mostly through rural areas. I wouldn't have made it to any tesla charger by far as they are not as available here in the UK as US (yet)... I diverted to the closest major city ignoring my route and diversion hoping there was a 3rd party charger. Thankfully there was and after a 30min downloading the app and another 60min sitting in my car at 1 am I was finally ok to move again. it was a lesson learned. I have a model 3P ..and I wouldn't change it either.
