After 9 months and 7000 miles I finally used a valet. Leaving the car: Me: "I really LIKE this car and I want it to be in perfect condition when I get it back. Have you ever seen one of these?" Valet Kid: "Oh yes, we get a lot of these." So I put the Tesla Tap Valet Instructions on the browser in full screen. The first line is something like: Welcome to the Tesla Model S electric car! Getting the car back: Me: "Thanks, is it running out of gas?" Valet kid: "I don't think so. It seems to have plenty left."
