I've driven skylines (silver 33, yellow 34, and Golgo here and there) around metro Melbourne for a good 2.5years and 50-60,000kms and not once have I had a single problem with the cops, people giving me dirty looks or any "idiots" trying to show off in front of me. I'm not a granny about it either, I've had my share of speeding tickets in my younger (Ps) days.
I travel through areas like Greensborough, Ringwood, Epping, and down to Mulgrave quite regularly so I have to ask, what are you guys doing on the roads to provoke this reaction? Or if it's not you - list some areas where you're getting this a lot? I just don't understand how you guys get hassled so much!
