It's true. Asians often are awful drivers. I'm a gifted exception.
But you're right about the comment re: assumption that only Asians modify their cars. WTF kind of Asian kid puts hydraulics on his car? Good thing Asians have thick skin. Heck, what if you put Chicano Outreach Program at the top of that webpage? How do you think that would go re: accusations of racial profiling?
Last time I looked around here in LA there were lots of Latino-looking people driving lowered cars with tinted windows, altered lights, thumping stereos, no bumpers, and modified exhausts. (Maybe they're just trying to look Asian?)
I also noted that they've recently changed the law. I once got cited for VC 27151 (modified exhaust). There used to be a 95 db standard. That's how I successfully challenged the ticket. The officer heard a louder than stock exhaust, so he wrote me up. Interestingly, despite how the state claims you can have your vehicle tested for compliance, in actuality the state has no provisions for actually testing the noise of a car. So I bought a decibel meter at Radio Shack and tested my car, myself. However, now there's no evidence other than the officer's personal judgement as to what constitutes louder than stock.
