i have driven plenty of hot and loud and attention attracting cars, including a 106dB-at-idle large EP RX7.
i have been pulled over more times than i can count.
not once have i left a "random license / breath check" or a "you were doing 64 in a 60 zone" with a yellow or a fine.
it's called the "d1ckhead test". they're bored, end of shift, need a quota...whatever. that's not their fault. just don't have an attitude when they pull you over to give them a reason to say "pop the bonnet, please".
saying dumbarse things like --->
"oh for fukcs sake, this is the third time i've been pulled over in as many days - this had better be good"
or
"don't you guys have some granny bashers to arrest"
or
"another random license check?"
<--- will only land you in the "d1ckhead" category, and the following "pop the bonnet" request.
if they do ask you to pop the bonnet, don't be the aforementioned d1ckhead and say things like --->
"you won't find anything"
or
"don't scratch the paint with your buttons / badge when you lean over the car"
or
"don;t touch anything under there okay? i've just had this thing tuned"
<--- or anything really stoopid like --->
"i'm yet to put this over the pits"
or
"funny thing, i'm just driving to the inspection centre, like, right now...!"
if the officer inspecting under the bonnet says "is that an oil leak?" or "what's that?"...for gods sake, be HONEST.
responses like --->
"i've never noticed that before - maybe it's overspill from when i changed the oil last sunday"
or
"i dunno - the guys at the pits said i needed all the factory emissions equipment so i had to source all this crap that have no idea what it does - so i'd guess that'd be some of that"
<--- will generally see you with a low grunt or a "hmm.." and move onto something else.
put up a fight before the process has begun and you will get stickered for stupid things like chrome wipers, aftermarket guages, detailing wax on the windscreen etc etc.
just be patient. if you were driving a white automatic excel you wouldn't have this problem, would you? so don't think they DON;T have the right to pull you over, because they do. they have an obligation to save a lot of morons from themselves, and potentially innocent motorists and pedestrians.
pass the d1ckhead test 3 times and i guarantee the only people pulling you over are power hungry rookies with "sarge" in the passenger seat calming him donw just having a gander at your car.
then there's the highway patrol - they're a whole other kettle of pigs .... er, i mean fish.
