I don't know what I was thinking about (not taking care of myself in a dangerous and hostile environment, anyway...) I was stopped at lights I stop at most days. There's a straight on light and a right turn light. The straight on light was red, so I stopped. The right turn light was green, so the right turning vehicles were going. This is usual.
The right turn red light went red, and for some reason I took this as an invitation to go. I was fortunate that I was not flattened by cars coming through on the light that had gone green, which could well have happened. I got halfway across the junction and realised what I'd done... so I stopped somewhere safe(ish) until my light was green.
I'm really very sorry. What should my penance be?
How does this sort of thing happen? I mean, is it just the fact that road use becomes so routine that we "turn our brains off" until something goes wrong?
