Maybe Tesla can make some plastic, wallet sized cards that give instructions for valets. One side in English the other in Spanish. I used to have a hidden kill switch in a '96 Accord (I know you are all jealous) that stopped six theft attempts and every valet. The Model S might need some instructions for the uninitiated.
I have a first model year Lexus 400h (2006), and it came with several little instruction cards for valets in English and Spanish. It had a hole to attach to a key chain, like a CVS card or something similar. Very helpful that first year or so until hybrids became more prevelant.
