Yes. And... NO.
I believe Tesla is constantly evaluating themselves and their processes both internally and externally. They are always looking for a
'better way' to do everything. Not satisfied with
Consumer Reports declaring the Model S
"The best car we have ever tested..." they have been constantly improving the car on all fronts. Elon Musk noted those changes had continued at a rate of around twenty per week, and he said that over a year after
Consumer Reports' review.
That said, Tesla has also learned what processes do NOT work well and has certainly abandoned them in many cases. The point is that they don't simply presume something will not work without evidence that proves that to be the case. You can't change the world by doing things the same way they have always been done. Either by others, or even yourself. You must adapt to the data you have before you and act accordingly to change course as needed as a correction that will get you to your intended goal.
Oh, there are reasons. They just might not be of any concern to you, personally. One must recognize that not everyone feels the same way, or is as comfortable purchasing unseen as you or I may be. This is how I replied to a similar query:
Redmiata98 asked, "Hmm, they did not do it with the X, why do you think they will with the three?"
I think it is more necessary with the Model ☰ than with any vehicle Tesla Motors has released thus far. Not so much to get new business, or even to confirm current Reservations, so much as it is to prove they are a 'REAL Car Company'. It would be a great way to shut up the incessant Tesla Naysayers who have claimed since, like, FOREVER that Tesla would NEVER release a mass market car. Plus, there are people who really don't 'see' things on a computer monitor very well (I used to work with someone who had to print out all their e-mail messages to read them), they literally have to see things in three dimensions directly before them to get a sense of scale and reality.
It wouldn't take much to manage. There are currently about 99 Tesla Stores/Galleries in the U.S. If Tesla manages to prevail in their court case against Michigan's Regulators and Elected Officials, they may be able to double that quantity through this time next year. So, they could send two cars to each location, a total of maybe 400 vehicles as demo cars by the end of 2017. Since their goal is to reach as many as 500,000 units per year, at 50 weeks per year, 400 cars comes to only 1/25th of a week's Production. And, those demo cars could be replaced periodically as they were sold at Retail. One car to sit in the showroom, one to use for test drives in the Real World. When the test drive car is sold, the showroom car is put into test drive service, and a new showroom car is Delivered. Tesla loses nothing.
This was just part of my reply. Here is the link to the whole thing if you'd like to see it:
