Apparently you don't need to return EVs charged, so it would've been less hassle for me on my most recent rental. I had a car for 4 days in Las Vegas and drove around 250 miles total. I had to go out of my way when dropping it off for the flight to find a non-gouging gas station and stop there, whereas with an EV, I wouldn't have had to do that at all. Would've saved me $40 in gas too (which was 20% of the rental cost).
