I'm wondering what may not work in the model 3 if you live where the is no cell connectivity and very poor GPS signal and also travel to areas with similar connectivity issues. I have a family member with a model S 100D and noticed the main display map does not display the roads and sat images when driving to my location. Of course, the cell phone app is also ineffective when there isn't any internet access. A side effect of the unmarked mountain roads in my area is that EAP will be essentially useless. Any other considerations with Tesla ownership in this situation in general or specific to the model 3 anyone can think of? The car should be able to join my home Wifi network for connectivity when in the driveway.
