I've rented a lot of cars, but when I got this one I spent ten minutes completely dumbfounded trying to get it going. They gave me a key card but I couldn't figure out what to do with it. Swipe it, I guess, but where? I tried the door, but the pillar? Would've never guessed until looking online. Pretty much all other cars have keyless entry with a push button on the handle. I couldn't figure out how to adjust the side mirrors, which I always need to do in any rental, until I gave up and looked online.
Oh and when I got to where I needed to go, I left the car unlocked because I couldn't figure out how to lock it out or even whether I had locked it. I might have even left it running so that someone could have driven it off, for all I know.
I am very used to Android Auto in rentals, which I love because of easy access to the places that I care about (vs the last place than some other rental customer went to), the music that I care about, and the voice assistant that I'm used to. Instead I found the Tesla screen beautiful but distracting and useless without Android Auto.
It felt like a design very focused on eliminating hardware controls that are commonplace on most cars - very unusual - and with a strong proprietary, "we know better" bent.
So I feel like if you're going to have EVs in your rental fleet, maybe a Hyundai or Kia or Chevy is a better choice than Tesla.
