Wow, CA highways must be like a scene from "The Road Warrior".
Out East everyone gripes about aggressive SUV drivers as well as the BMW and Audi crowd. I'm assuming the mix of vehicles differs when you get into the snow belt; with shifts toward snow worthy vehicles.
From what I see out East, a lot of the young tuners are setting the trends in the aftermarket and even with the OEM's. To me it is very positive. The OEM's are offering lot's of powerful front and AWD drivers now. I see a vibrant car culture now as opposed to decades past. Plenty of room for everyone.
Sounds like CA has hordes of car gangs spoiling an otherwise good thing. Maybe CHP will step up patrols if enough people complain. Out East the Staties use unmarked patrol cars. Very stealthy.
Even minivans and SUV's.
