So what you are telling me is that this owner will never park their car in a parking lot because then other people would see it right? Again- other than saying its not my car and parroting the party line, there is no good reason to do this other than Tesla doesnt want people canceling their orders because they finally get to see the car in person and don't like it.
Hmmm... I agree with you in principle, in practice I would side with Tesla. The delivery team at the service center is in charge of getting that car into the hands of its new owner in the best shape it possibly can be. I know if I were tasked with that job, I would not let anyone other than my team/ employees or the car's rightful owner within 50 feet of it. Even if you know they just want to look at it and not touch. Behind closed doors in a service area, where customers typically are not allowed anyway, or behind a fence in a holding lot, even better. Having spent time around a lot of car dealerships myself, I can say this is common practice anyway. As soon as a car is pulled for a customer, it's a total hands-off situation for everyone else. Some dealerships don't subscribe to that theory and it sucks.
I'm pretty sure it has nothing to do with not wanting to let people see the car. It's about liability and and maintaining a consistent policy for delivery and the handling of new vehicles. If they didn't want people to see the cars, they wouldn't be offering the Meet the X tour. Even with that, they're not even taking the time to address damaged seats and FWD sensor issues.
Of course once a customer takes delivery, it's going to be out in the wild with people touching it, peeking into windows, trying to inspect the inside. It's going to be a problem actually, at least until the car becomes more common. My wife is stressing out about the FWDs and opening them in public. In a way I am too, I'm not really a people person. I have no trouble showing it to friends or other like-minded people on these forums or such, if something is arranged. However, that's the worst thing about driving flashy cars or collectors cars or whatever -- the crowds they attract and everyone wants to just look and the next thing you know, they're climbing in and pushing all the buttons and adjusting seats. Tesla is avoiding that, they're just not going to budge on this policy, not while the car is in their charge. Once the car is delivered, that is up to the new owner and how they handle it. When the car is still in Tesla's care and on their property, they're going to dictate who can see it and why. FWIW, they don't let people go up and look at other peoples' roadsters or Model S's that are in for service, either.
