I'm puzzled by the signage now being used on our motorways.
25 minutes to J15 means nothing if you don't know where J15 is.
Even 11 miles in 10 minutes doesn't help that much. That's 66mph. Is that the best that's possible weaving in and out? Not terribly significant in any case if I'm plodding along at 55mph.
It strikes me that a better system would be just 3 levels
Red = Stationary Traffic
Amber = Congested
Green = Free flowing
