“Tesla can promote the car at airports, trade fairs, Olympics, and other special events.”
I would argue that this constitutes Restraint of Trade, in that Tesla would have to incur the added inconvenience & expense of constantly moving their vehicles and employees from place to place. Additionally, they would not be likely to have the same exposure to potential customers, as compared to their current way of doing business.
At the extremely upscale Short Hills Mall in NJ, they have–literally–thousands of very wealthy people walking past their display windows every day, and a goodly percentage of these folks stop into the “store” for more information, or just to sit in the cars. This strategy must be working, because I am seeing an increasing number of these cars on the road in my area. It will be a while before they outnumber Porsche Panameras, but the number of Teslas around here is growing fast.
