What not to do while driving

Below is a list of things you should avoid doing unless you want to annoy other drivers on the road.
(Note, this list was written by an Australian living in Australia, where we drive in the left lane)

• slowing down to turn off before you indicate
• going the opposite direction to which you indicated
• indicating to go follow the road
• not indicating to get off the road
• not indicating at all
• leaving a massive gap in front of you when waiting for a red light
• stopping in front of a T intersection far enough away from the intersection so as not be able to see incoming traffic
• taking up the entire road to turn right at a T intersection
• stop in the middle of a single lane road with no hazard lights on and no apparent reason
• decorating your car with 50 'L' plates
• decorating your car with green and red P plates (at the same time)
• trying to turn left into a suburban street from the right lane of a main road
• driving in two lanes
• tailing another car which is trying to find a parking spot in a parking lot
• leaving your high beam on
• talking to your friend in a car which is going the opposite direction, in the middle of an intersection
• tapping your brakes
• driving (swerving all over the road) with your knees while eating

If you have any more you'd like to add or think that some should come off please feel free to leave a comment below :)
