This was the lovely message I was greeted with on the M50 matrix board this evening! WTF? "Everyone behind would suffer if you slowed down" would be more accurate I think

So who thinks up this garbage? Especially as the M50 just crawls along half the time, the last thing we want is people going slower

And why don't they default all these boards to something useful? Like "Keep in the lefthand lane when not overtaking" or "YOU! Use your feckin mirrors numbnutz! :@"
