I'm really happy to see this ruling.
You shouldn't be. Now they are going to take longer to write your ticket ("I'm sorry sir, the computer system is slow today...") while the dog is en route or they will manually search your car because "you looked high." "Is that a bottle in the back? It looks like an open bottle. Please step out of the car sir." "Why are you reaching for your glove box? I didn't tell you to do that. Put your left hand on the wheel and open the door, slowly, with your right, right now."
Hot Beaner/ricer cars will get you flagged. (I drive one too.) But after your insurance and license checks out, it mostly has to do with how you relate to the officer. Use sir/ma'am a lot. Apologize profusely without admitting guilt after they tell you what you did wrong. Look them in the eye when they talk to you, but don't do it defiantly. Reach for your wallet and registration slowly, and tell them you are going to do it first. Keep the inside of the car looking neat and remember that if you want to look like a gangsta, you might actually get treated like one.
They're just pulling a string to see if it looks promising. Are they stereotyping you? Sure. Beaner/ricers will get pulled over so they can search for drugs. They'll pull over white women in Beamers after lunch and dinner to see if they look intoxicated.
Remember that the police have tremendous latitude to fuck with you or fuck up your day/week/month, if properly motivated. Even if you ultimately win, your lawyer and court trip will cost you around $5K. So try really really hard to convince them that you are not a problem. That doesn't make it fair, but they are people too and get grumpy. Especially when they make $40K, spend all day in a small car carrying 40 pounds of shit on their bodies, generally deal with assholes (best case) or people who want to kill them (worst case), and have traffic stop quotas.
