U-locks offer similar protection but are much more difficult to attach to something, that's why hardly anyone here uses them.
And my favorite story of bike theft came from a guy in Amsterdam who had his bike stolen: the guys who did dressed up as city workers and simply stole every bike that was locked up in a place it shouldn't have been, and not a single person was the wiser until they went to get them out of impound and the police had no record of them being removed.
