As I have been traveling last year, I've seen several promotions from car rentals to get an electric car. Never took it - first of all, I don't want to drive Tesla because it's not safe (no physical environmental controls, which means, especially on unknown roads, distracted driving, not worth the risk), but I also don't need the trouble of figuring out where I can charge it, would the charger fit, etc. I know with a gas car I can use maps app to find a gas station, it'd probably be within 10 minutes drive and it will work, and I'll be on my way in 5 minutes after. I don't have such guarantee with an electric car. Also, I've been recently on a trip with a friend and they rented an electric (not Tesla). We had to build all our plans around "where can I charge it".

I'd probably go for a hybrid, since it doesn't have any downsides like that, but not for fully electric. Of course, it's just my own opinion, but I suspect there are a lot of casual renters that are like me, and Hertz is seeing that.
