sigh this has been discussed ad nauseum
it depends on a combination of what you drive like, how you look, your attitude to the cop once pulled over and the cop themselves. yes our cars stand out from the bland taxis and 4 bangers, so we are more noticeable, plus our cars have a reputation due to the small amount of dickheads who do hoon on the road, i reckon we don't get it any worse than rexxies or supras though
As a rule I don't drive like a tool on the street but...
for eg. pulled over in an RBT when I had my r34 GTT, did the breath test then told to pull up a bit further to pop my bonnet, cops tried to ping me (had an exposed pod at the time which came like that from japan) but I didn't act like a tool, they let me go with a warning but told me to get the pod covered/engineered etc etc
also when I had the 34 operation taipan pulled me over as I was cruising along on the great western highway where the minchinbury maccas is, (not to mention he swerved in and out of traffic to catch up to where I was & had to speed up over the limit, i saw his sirens as far back as the BP servo, ironic) he got me to pop my bonnet, again just a warning to drive safe (yeah sure, when I was cruising at the speed limit & you drove like makkinen to get & pull me over) and sent on my way.
