My main concern with this is can they dob you in for speeding (not that we do)? But hypothetically say you pass another car at 65 in a 60 zone and your in your skyline and the person you pass hates skylines because of all the media attention. They then dob you in and say your hooning past at 100 in a 60 zone can the police get for 40 over im assuming they need alot more proof then just their word. Otherwise why do police need lasers, radars etc to book you for speeding when jo blow with no prior training can say i saw them speeding at XX kms and then you get done.
