This is funny too : Wait till dusk / night-time. Park the car up a reasonable distance from a speed camera that has foilage nearby. Walk into said foilage. Set camera to 'Red Eye' mode so it does a double flash. Wait until a car goes past at normal speed coz he KNOWS the camera is there and doesn't want to get caught. Take photo. Watch brake lights come on and car slow down to 10mph. Spend the next week at work giggling to yourself that there's a dozen people out there pooing their pants every times the postman brings the mail ;-) Not that I'd actually do this of course.... (",)
