Clear the streets!

Something rare happened today. Martin and I was going to The ICA Institute next to Green Park, to see an exhibition, and we went on bikes. I was quite nervous about driving my bike in the center of London. The traffic around London is less than bike friendly, so going to the center would really be a test of my traffic abilities. But do to a big protest against education cuts, the streets in the center was left empty.
Wouldn't it be nice if it was like that every day?
