when i was coming home one night i had a p plater in his commodore sitting right up my arse, and he was really close so i tapped the brakes and he moved a little then i did it harder and he had to swerve to miss me he shat himself because he backed off a mile, then it went double lanes and he booted it thinking he was cool. and thats how you get rid of them, because if they run up your ass they pay for it and you can get really angry and bash them up.
