A) Plan ahead so you don't run out of juice. EVtripplanner.com is a great site for this. For my early road trips in the Tesla (when Supercharger density was much much less than today and the car didn't have the rout-based range estimate built in…), I would ID RV parks along my route that I could use in a pinch, and would go into EV Trip Planner to see what the rated miles estimate is to the next planned charger -- and I would decide if I could make it as I passed those check points (and we never needed to stop -- but it does take a road trip or
B) If you are concerned about range -- slow down. Driving over the limit will give you less range. Slowing down to 5-10 under the limit can do wonders for range. We had a road trip almost a year ago where we needed to go 190 actual miles, with a prediction of 205 rated needed if driving the speed of traffic (I have an original S60, so my max range has degraded a bit and is ~192 rated). We drove 10 under the limit for the first 1/3 of the trip, then drove the limit the rest of the way -- and we made it with 10 rated to spare.
B) If you get low, find a charger, RV Park, or even a 120V outlet (and keep your UMC and adapters in the car on road trips).
C) Call Roadside assistance for a tow
D) Some AAA members now have charging trucks (I know at least in Seattle…). They can send the truck that has a generator and a J1772 port and can help you charge for 30-45 min (hopefully not longer) to get enough charge to get to an actual charger
