"In the United States, the strategy would be to leverage, would be to tie to patriotism and shift to the right," said Eric Schiffer, chief executive of private equity firm the Patriarch Organization in Los Angeles.

"The European strategy is going to be more challenged and will need to be more about the value and competitive differences with the market there."

Nonsense. Europeans love patriotism and the right too. The real problem is probably that Musk came off as too American and not European enough. No doubt his salute was mistaken as being the Bellamy salute. All he needs to do is make the next one a little more explicitly European, maybe add some stirring phrase in German or such to really drive things home.

Tesla uses white, black, and red color scheme in its logo. These logo colors help convey the brand message to the target customers of the company’s electric cars. The white background is contrasting and makes black and red colors more visible. 

Maybe do an armband up in Tesla colors to get buyers really excited!
