Well, as an example, today I was coming out of Kettering, and the gantry was crying “M6 JCN 2 TO 3 VERY LONG DELAYS”…
■■■■, I’m going that way, not good, what are the options. Let’s consult the maps, and look for an alternative route. (Whilst doing 56mph on the A14… 
)
No wait… next gantry is dark.
Guess what…
Nothing happened…
