Hiplok: A new hipster lock

I know two people who cannot cycle now due to falling onto their lock, one did it when he was really pissed.. Easily done.

I still don't understand why cyclists do this. The first thing I was taught when learning to ride motorbikes as a kid was keeping locks and heavy stuff away from you in case of a crash. The idea of a disc-lock impacting on your ribs in a crash is enough to dissuade me from ever, ever wearing a lock on my body.
