[QUOTE 5315549, member: 9609"]I wonder how barking mad it would become - on a 60 road there would be those who would choose to drive at 55, and there would be those that would have to overtake, and of course half way past, Mr 55 speeds up to 60, and Mr 60 who is now hung out on the wrong side of the road completely looses the plot and refuses to abort the overtake - round blind bends the lot. we would be seeing levels of road rage never previous encountered.[/QUOTE]
I think there’s a black box based solution that is more like the solution insurance companies offer younger drivers already. Don’t actually stop cars from breaking speed limits - but hit us in our pockets, hard, every time we break a speed limit, every time we accelerate more than some specified g’s forward or backward or round corners, etc.
It needs a legally reliable map of speed limits. Then the next step that opens up is variable speed limits everywhere - lower in wet, lower after dark, lower in traffic, all indicated real time via the same legally valid gps-linked map.
