I think the P90D/P100D buyers are not the types to necessarily by a Charger or Challenger. They're fun cars but a bit louder... just got a 2016 392 Scat Pack Shaker Challenger a few months ago, very fun car... but not in any way similar to any Tesla. It's just a different feel.

That said, most aren't in a position to really push their cars, and they don't... It's mostly bragging and any car with a 0-60 under 5 seconds will give a lot of that fun.
