With regards to rest stops and my personal habits, I used to be of the opinion that it would be useful to put charging stations at them, (in an ideal world, if you ignore the legal situation). However, the first issue with that is that rest stops are always crowded these days anyway and putting chargers in would exacerbate the situation unless you also create more parking spots.
The other issue is that its popularity and temptation to stay there an extended period of time if they were level 2 chargers would make state enforce their limited stay rules more vigorously. Right now, I occasionally like to drive through the night then, just as dawn is about to break, pull into the next rest stop and sleep in my car for an hour or two. There might be enforcers at the stops to make sure people don’t sleep there overnight in order to charge and then they may as well also police the regular people who are just trying to sleep in their cars.
However, on my recent road trip I did notice a lot of chargers at midrange hotels and truck stops. I re-measured the trip to see how it would look like on a midrange EV getting say 200 miles to the charge (assuming a slight improvement in range over the next few years, but recognizing that I wouldn’t splurge for an expensive Tesla.)
First leg: St Louis: over 1000 miles. Even assuming a full charge at the start, and 1/2 hour charging at level 2 stations at hypothetical rest stops, it would require 3 stops of almost 1/2 hour versus 2 stops of 5 minutes. So a definite negative there even in the best case.
Next 3 legs: between 260 and 310 miles. The last leg would require a recharge stop regardless, but the smaller ones might not, all depending on the availability and speed of chargers at places I stopped at regardless of the need for a refill. So it might have been worse, or better, than gas, depending on how things work out over the next few years.
Next leg: This was a light day, less than 200 miles, but ending in the middle of Allegheny National Forest a couple dozen miles from a place that would reasonably have a charger. So if the places I stopped at during the day had chargers, I could end the day with enough juice to get to one, but would have to refill as soon as possible.
Next leg: 200 miles and I didn’t stop anywhere along the way. I would have had to make one extra stop due to not being able to charge overnight the day previous.
Next leg: 50. I get that one for free.
Next leg: 400 miles. I did stop once at a Target, so if they had a supercharger I might have only had to stop one time, just like I did in actuality, so only losing the difference between a gas stop and an electric stop.
Next leg: 900 miles. I would have had to stop 3 times versus the 2 times I did.
So in short, I would have had to make at least 2 more stops, and take longer making those stops, than with my HEV. And that’s in the best case scenario. However, if I had a house, that would be worth it to experience that twice a year in exchange for rarely stopping to get gas the rest of the year. Outside of the best case scenario, (i.e. if few places I would have stopped at anyway had chargers, and if some of the hotels also did not,) it would have been really annoying and would have put a damper on my vacation. It still might have been worth it, but not having a house, I can’t really say.
