Turn Right
Do you hate it when the driver in front approaches the give way lines, at a side road T junction, to turn right onto a main road. They stay about three feet away from the centre line and about the same from the give way lines. You want to turn left, and there is no traffic coming from the right on the main road, but there is continuous traffic coming from the left on the main road preventing the car in front turning right.
Because the car in front is positioned so far in from both sets of lines, you can't squeeze through between the car in front and the kerb to make a simple left turn, by the time the car in front has made their manoeuvre there is now continuous traffic coming from the right on the main road, preventing you from turning left.
