The fact that somebody else does something has never seemed to me like a particularly good reason to do it too. A lot of people bought Mk4 Ford Escorts. A lot of people watch Saturday evening TV. Yet the other day I spotted a motorway matrix sign urging drivers to ‘Bin your litter’, simply because ‘other people do’.

Now, normally I like overhead matrix signs. They are useful. Drive often and you’ll learn their language, too. ‘Long delays’ is pretty much shorthand for ‘Motorway shut’ and means you should detour. However, if ‘Long delays’ some way off become just ‘Delays’ as you get closer, it has reopened and might just be ‘Congestion’ by the time you arrive. Or, if you stop briefly to part with four quid for a cheese sandwich, it might even be completely clear. 

Yes, sometimes they’re wrong, and Google’s map app 
is better still at estimating a 
time of arrival, but you can’t look at that in lane three of 
the M6. Were it not for these signs, I would have spent many more stationary hours sobbing into a steering wheel. I have seen ‘To J16 (M40), 15 miles, 50 minutes’ and known it to be accurate so many times that it’s one of the reasons why I want to move to somewhere where the mile-to-minute numbers show distinctly more parity.
