Well, there are many reasons. Some people
Don’t live near a service center. Also, tesla has been very slow in filling these orders. In my case I did order it from Tesla, in June. I then emailed them to ask if mobile
Service could install. A month later I received a reply that they had no record
of my order, I immediately replied with a screen shot of my confirmation email. Then I heard nothing. After two weeks I emailed
Them and asked them to cancel. Since I really wanted it, and don’t mind taking my bumper off, I ordered it off eBay and installed it. Now I just need them to activate it. Had I gone the eBay route to begin with, I would have saved a lot of time and frustration.
