I don't get the key or fob issue but I don't have my 3 yet. I don't understand why you have to have a key or fob for using a valet. I also don't quite understand the need for a key to access storage as was stated in the video. If I use a valet I can put the 3 in valet mode and hand over the card. What is the problem other than an uninformed valet? A valet parks cars for hours and hours every day. I think they will figure it out after they see a few dozen 3s. It makes little sense to change the design of the car to accommodate the learning curve of a valet.
I don't think I want to give the valet a fob that also opens storage. Are they suggesting a fob for vehicle access and a different fob for storage access? It makes no sense. The card and Valet mode solves a problem, why go back?
I listened to EVTV and Jack Rickard goes on a hilarious rant about the enormous problems and expense with getting a model S fob replaced. Possible strong language alert.
See 19:30 minutes in.
The cards are supposed to be only $10. Jack thought the model 3 card was a brilliant solution. But Jack did complain about intermittent operation of the smart phone app. In the a followup video it turned out that the problem was resolved by not having multiple copies of the smart phone app trying to access the 3 at the same time. The 3 seems to lockout the smart phones in some cases if I understand it. Watching EVTV can be a little like watching "slow TV" but he sure gets into the nitty gritty technically. Good stuff you won't hear anywhere else.
Were I to have a 3 I might be able to make better sense out of the CR issue with the cards and valets but my bet is that in 12 months other car manufacturers will be copying Tesla. In 18ish months the model 3 will just drop you off and park itself and no more valet problems<grin>.
I am happy to say that this week seems to be a week where Tesla made substantial progress. The Boring company info was great and the SpaceX Shotwell interviews were great. Progress in a world that needs it.
