“Spray – Slow Down”, read the big illuminated warning signs above the motorway. It’s raining, and the M27 being badly surfaced as it is, is collecting enough water that every vehicle is sending up huge plumes of spray. People are slowing down, too. But they’re also driving closer together in proportion to the amount they’re slowing down. So they can’t see anything for the spray of the car in front. I’m wondering if the signs should read, “Spray – Keep Your Distance”, but what would I know?
