| Accident "Black spots" as you call them, can be to do with some sort of physical feature of the road layout, that we fail to prepare for. The lack of planning for which is usually after a long straight.
So remove the causation factor of the excess speed on the long straight, and we make it through the difficult bit!
Funnily enough though, we still manage to have collisions on the motorway, and they are fairly long and straight. |
