I'm not worried about it. There's apps and websites that show you all the charging locations. You have to figure out much more complicated stuff than that while traveling.
I'd love to get an EV rental but I'm not willing to pay extra for it and luck hasn't smiled my way yet. I also don't use Hertz, mostly Avis, and I'm guessing they don't have nearly as many EVs.

and what if the conference center/tourist attraction you're going to doesn't have a charging station? What if they do, but they're broken/occupied? I agree it's not an insurmountable task, it's just something I don't want to have to worry about while I'm dealing with the other "much more complicated stuff".
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).
