Recently I rented one again, and the process was much improved, which I take as an indicator that (despite this sale), they haven't turned completely bearish on Tesla. Counter-person much more knowledgable and agreeable. No mixups. Also, the software has improved. The rental now provides an on-screen tutorial on using the car, and you can now use your phone as a key. Huge quality of life improvement.
Hertz could still do better. They need fast chargers at their location. All cars should be available "fully" charged (80%) with no need to bring the car back full. And they need to get rid of that ridiculous key-cover for the physical key that prevents you from just slipping it into your wallet like God intended.
