Ok, we all know how frustrating it is to be overtaken too closely by a car, or get tooted at just for being a cyclist, but would you go so far as to throw your own poop at a car?

It was only in February when we saw a harassed female cyclist seek revenge on cat-callers by chasing down their van and ripping off the wing-mirror. The latest cyclist outburst on a vehicle happened in Gloucester when a driver's windscreen was struck with human excrement after the driver had beeped at a cyclist.
