What's more worrying is the amount of people driving around who seem to have no understanding of how a roundabout works.
Or any other junction for that matter.
This seems to be the procedure
Stop half a car length before the white line.
Wait there until one of the 2649678 drivers waiting behind you loses their temper and uses their horn.
This is your signal to increase your engines RPM to one less than the limiter, and slip the clutch to move the car to the white line.
Now you peer myopically in each direction until the helpful person behind hoots again.
This means you MUST panic, and pull out into the road with such a jerk that the car stalls when it is blocking both directions.
Using your years of driving experience, you now turn to the direction of the vehicle that is going to hit you first.
This allows you to receive the entire experience of being hit by an articulated truck at 25mph.
Maybe you don't bleed to death before the emergency services cut you out of the wreckage and load you into an ambulance.
