It was quite interesting driving home in light rain from some friends in the West Midlands last night. When it was raining, the wipers hardly ever wiped before the screen was virtually opaque with rain. So, as normal, I was clearing the rain with a single press before the auto kicked in.
Then a bit later on in the journey the rain had stopped, and the windscreen was dry, but the wiper went across about every 10 seconds when there was nothing to wipe! What a crazy system!
One other thing I noticed on the wiper controls, there is no “off” setting. They often have signs at tool booths (or the Chunnel) asking you to turn your wipers off so they don’t flick the wiped water towards the toll booth operator. So an “off” setting would be useful.
