Happily cruising down the middle lane of a motorway with either indicator flashing, but going nowhere.

Happily cruising down the middle lane of a motorway even when the road is almost entirely empty.

Picking your nose and believing that no-one can see you.

Not realising that there is any other setting for your lights than high beam.

Indicating to move into a lane that you're already half way in.

falling asleep at the wheel, just in time for the lights to turn green.

Sounding your horn one nanosecond after the lights change to green if the car in front hasn't sped off.

Sending sprays of wiper wash right over the top of your car and washing the one behind.

Overtaking then pulling in front and slowing down.

Sharing whatever is on your car stereo with anyone within a mile radius.
