On my last three road trips with my red 550, I've had Tesla drivers just go berserk after I passed them on the freeway. In each case they've been cruising in the left lane when I pass them going slightly faster in one of the other lanes. Never do I do anything to provoke them (well, one time I did shake my head!). Not right away, but after about a minute they come roaring up and get right on my tail, then pass with a flourish. They eventually get stuck in traffic when I don't, so I pass them again. They repeat. I never react, never change speed. But the last time when I tried to change lanes the guy tried to prevent my lane change. I try to disengage these idiots right away, usually by slowing down. I was only able to lose 1 guy by pulling off in the truck brake-check area on the Grape Vine. I refuse to race with these idiots. I've seen red-car-itis before, but what is it with these guys?
