That would be a great idea. I had my first experience with a valet last week. I tried to explain to him how to use the gearleaver and he just replied “ don’t worry this is my job and I know how to drive cars”. So I moved to the side and waited to see if the valet will figure it out. And yup took him around 3 mins ?. When I came to pick up the car, the valet called me and said the car would not start. Went down a floor and the car was still in gear when it was turned off and wouldn’t start unless it was set to park or neutral.
