My thing is I dont go to the ricer street race area's, they race in the ghetto (there was a video posted a while back about street racing, that took place in Hartford, CT, which is where the rice around me races) and I don't want me or my car to be out in that area late at night. I would rather not get shot.
The areas I go to, and people I hang out with drive Fbodies, Mustang, Vettes, etc... and for the most part they all go out and race. There are a lot of money races out here too, and the big $$ races always seem to have a Mustang or Fbody involved, and lately the other car would have been an STI or Evo (they got real popular real fast).
I have seen the ricers racing, seen the muscle cars racing, I have seen it ALL at our local strip (not race track, but street everyone drives on), and can say no one group is better than the other in their decision making skills.
