When I had my Leaf, the only behavioral issue I've noticed is that people would never get behind me at stoplights. I would look in the mirror and actually see people leaving me alone in my lane to join several others in the other lane. My guess is they think I'll accelerate away at a snail's pace (this is when Leafs were more common than Teslas). They got a surprise as soon as that light turned green.
Now that I drive one of the most anonymous BEVs in the world (eGolf) I don't notice any behavioral changes from people. I was even waiting for someone to leave a nastygram complaining about my "cheating diesel" but that never happened.
