I think this is one of the things that Toyota has done really right. Their hybrid drivetrain has made its way into a few models now (Corolla, Camry, Prius) and it's never a big thing, just a feature of the vehicle. I'm a longtime proponent of EVs and I've always hated the way that car companies feel compelled to turn any electric offering into a science project freak show.
To my mind this is the number 1 thing that Tesla has done right with their vehicles. They don't sell "Electric Vehicles", they sell vehicles. Which kick ass. And happen to be electric.
Toyota basically started this trend by making the Prius ugly and distinctive. Which is why Prius's sell very well but other hybrid drive trains in normal looking cars don't. You don't get cool points for driving a Camry Hybrid.
I dunno, the Insight looked pretty weird, with it's Citroen-esque covered rear wheels and its super-sleek exterior. But otherwise... I see where you're going with the "make hybrids/electrics look different so they'll gain cred" but it seems to be belied by most manufacturers' "here's a weird-ass dork car, you won't buy it right?" thing. Even the Bolt (which I'd argue is one of the better-looking non-Tesla EVs) is kind of klunky-looking.
I think they've even done one better. They've managed to associate, in the public's mind, the idea of "electric drivetrain" with "conventional but stunning good looks" with "amazing performance."
