I will never understand why drivers seem to be bouncing with rage so much of the time. They're sitting their in their comfy chair in a climate-protected room, listening to their favourite music as they glide through the roads - and yet they obviously hate the journey if anything that's going to slow it by even a moment causes them to weep and beep and screech.
Odd, too, that someone who will sit patiently for 20 minutes behind a tractor or a flock of sheep turns into a maniac if it's someone on a bicycle that's on the road in front of them.
