In my work as a peripatetic music teacher, I have had some pretty testing experiences as I drive around the county from one school to another.
I've been skating in my car: http://boingboing.net/2011/01/19/cars-sliding-down-ic.html
fortunately I had the road to myself. Unfortunately it was up a little hill. Fortunately I had very, very good tyres. Unfortunately there was a line of parked cars. Fortunately I made it to the top without hitting any.
Then I went home and recovered.
I've been swimming with my car. Several times. I've been luckier than whoever this poor motorist was - my car never actually drowned but my word, it was scary, scary, scary.
Now I can inform you that there will never be any seriously bad winter weather in West Sussex ever again. That's because I have just been given a folding snow shovel and a pair of snow socks for my front tyres.
In July. Now that's what I call thinking ahead.
