After reading through this thread, as a prospective future buyer of a Model E and a road trip enthusiast, I'm now thinking that I might be better off getting a Volt. It seems like too much hassle to have to McGyver up every conceivable adapter for every conceivable emergency scenario and have to use advanced computer simulation software planning my trip just to make sure I won't get stranded anywhere. This thread has brought up memories of a time that my fuel level got very low in a rough part of Detroit late at night coming back from a trip, due to me misestimating how much gas I had left in the tank. At least I was able to find a well-lit station, pay at the pump, put in a few gallons, and get the heck out of there.
Look at other threads too. Many more people run out of gas on a daily basis than in an EV. Yes it can happen but it doesn't take more than your UMC cable and 3 adapters that fit in the recessed area underneath the floor of the trunk you take a road trip. Bonnie has 30,000 miles and I have over 25,000 miles of EV driving and while I've gotten down to 10 miles one time I knew I was stretching the limits and was near charging outlets.
If someone is the type of person who has run out multiple times in a gas car and basic planning for a trip isn't a strong suit then even a gas car might not work out. If they've never come close to running out in a gas car then an EV would work too.
Of course the Model E won't be out for three years or so. A Volt lease would be an excellent step to EV driving.
