Very, very interesting commute this morning....
Temperature a couple of degrees below 0C.
Light drizzle of supercooled rain.
This hits the ground and promptly freezes over giving a beautiful smooth sheet ice surface.
Cars and pedestrians sliding all over the place. Sheffield city centre apparently at a complete standstill with people with broken limbs lying all over the place waiting for ambulances. (Or so SWMBO has informed me when I phoned to see how she was getting on - she could not get to work)
I passed a couple of "lets slide across the road and demolish the oncoming sliding vehicle" accidents.
Winter tyres coped fine; could not easily stay upright on my feet when I had to stop but once cycling it was OK
1 hour for the 15 miles.
I wear a helmet with a helmet cover to keep my head warm in these conditions and, by the time I got to work, it had accumulated a layer of crinkly ice all over...
