I've only encountered one who wanted to make it known to me that he's in a V8 muscle car. That's just one compared to oodles more Mustang drivers and even some Camaro drivers. Most Challenger drivers seem very laid back and secure in their car choice, which is fine by me!
Haven't had much issue with Chargers. I think around here they know their place, despite the gaudy paint jobs and stripes.
Basically a family-hauler for dads who yearn for the V8 muscle. At least they're not in minivans, I guess.
