A very long time ago, when I was driving the Zap Xebra (for reference, Tesla was developing the Roadster at the time) I had a friend who named his cars. So I decided to name my Xebra Yvette, for E[lectric] [Cor]vette. Forget zero to 60. The car couldn't do 60. It did zero to 35 in about 31 seconds.
But I was never comfortable calling my car by a proper name. So I quit. I didn't name my Roadster and I have not named my Model 3. I briefly played with the idea of naming it George. William Herschel, the discoverer of the planet Uranus (or was it Neptune? I think it was Uranus) wanted to name it George's Star, for King George, but the astronomical society wouldn't let him. So poor old crazy King George didn't get a planet named after him. Seemed only fair to name a car after him instead, except that I was never really into naming cars.
So the name George is still available if anybody wants to use it.
