Tesla has to have it on there because it was crash tested in place. The story widely reported is the crash testing requirements only allow for a certain dollar value of damage ($800?) and the Model S hood kept getting damaged in the low-speed test without the bracket there. So they MUST sell it to you on there. They cannot remove it by law. If you don't buy the car, they must have it on there for the ultimate buyer. It's akin to the little ugly black rubber bumperettes Porsche installed on the '80s 911's to get it to pass. Thankfully, Tesla didn't put screws through the bumper.
