Box not clever

Do not enter the box unless your exit is clear. What's difficult to understand about that?

So there I am this morning, sitting in my highly-trained Korean hatchback at the head of a red light queue waiting to turn right. When the lights change, traffic tailing back from temporary lights further down the road I want to turn into means that half a blue van is already in the box and my exit is blocked.

I sit tight. Someone behind sounds a horn, having nowhere to go I ignore it. A few seconds later it sounds again, then a young woman in a silver Clio - personalised reg of course - pulls out from about 3 cars back, overtakes the queue and drives into the middle of a blocked junction. Unbelievable.

What are some people thinking? Why do they believe they're more important than anyone else? And who did they get to take their driving test for them?
