Fair calls on all of the above...
I am of the opinion that the police do tend to target the import "hoons" over drivers of standard cars. In the first 6 months of owning my R33 I was pulled over on the Hume Hwy just inside Goulburn by HWP. At the time I had green P plates, it was the easter long weekend so I of course was doing the allowed 100km/h. I was defected for the usual, exhaust, BOV, ride height etc which I took gracefully. However, it was partially my fault as I did not check the engineering certifiacte against what was on the car when I bought it.
In saying that, the thing that really got me was at the exact moment I went past the unmarked HWP a red P plater was speeding past me doing well over the speed limit and I was the one that got pulled over. The cop's reason...? "I heard your exhaust it seemed too loud, nice car but!"
Even though at the time I had my exhaust engineered for the allowed DB limit!
The thing that really gets my goat is the fact that there are SO many drivers of standard vehicles out there who are the ones driving like idiots but of course the majority of police turn a blind eye to this and focus on the import "hoons" which unfortunately due to past incidences has landed us that stereotype.
