I'm driving home from Costco and I pull up at a stop light next to a brand new grey P85D with grey turbines (still Tesla paper plate on the back). Roll down my window to congratulate the owner on their new car. I give him a wave, he looks at me...and...rolls his window up. No wave. No acknowledgement. I know Teslas are a dime a dozen where I live (Orange County), but damn, man...that's not cool. A year ago when I first had my car, I'd share an acknowledgement, nod, or wave with literally every single Model S I encountered on the road or in a parking lot. With Tesla's growth and expansion, the camaraderie amongst Tesla owners seems to be fading. It doesn't surprise me, but it makes me sad.
