I mostly agree with JAR.
I also like to mention the "random checks" are quite random
They always seem to happen on the Skyline, but never on my parents Commo, yes quite random given that I drive my the Como 95% of the week.
I know there is nothing we can do but I do believe the stereotype of young male driving turbo import is a hoon is wrong. Though I would like to admit that I drive more "hoon-ish" in my dad's Commo rather than the Skyline (trying to keep the image of Skyline drivers clean, I don't know why I bother with so many dickheads around but).
I was also driving the Commo on bald tyres, low pads, and thin rotors (due to lack of funds) for a while, but hey no random checks for a safety hazard to other road users... I'm guessing the number of clicks on my Skyline's handbrake, or pod filter or some other bs they look for was posing a higher risk to other drivers and pedestrians around me.
