They'll occaisionally pull in behind me but if I just putt along like a grandma they usually piss off pretty quickly.
This morning I got lit up less than 30 secs after pulling out of my driveway.. was like 5am and I was heading to a paintball tournament, unmarked car was coming down my street slowly with the highbeams on (i thought it was either cops or a taxi), I back out of my driveway and head down the street directly opposite quite slowly as car was still a bit cold. Cops belted round the corner and sat on my ass, I was like "ahhh here we go" then the lights come on, I pull over, they hover near the back of the car checking my rego, when they realised I lived less than 100m away they pulled up next to me and go "sorry mate, there's just some shit going down in the suburb this morning" I was like "yeah no worries guys cheers" and drove off.
It actually gave me a good feeling about the cops for a change
