One of the reasons why I love commuting by cycle is well demonstrated in this little clip.
This isn't by any means a big queue at this junction. When the local school finishes, cars (usually with one adult occupant and one child) can wait for 20 mins or so to creep forward and turn. I am 4 miles down the road and locking my bicycle up by then!
And some recent experiences demonstrating what I don't like. In all of these clips I was wearing hi viz reflective gear and had twin front and rear flashers.
