You know how those lock picking videos are made, right? A hobbyist spends a couple big on a disc detainer lock pick tool calibrated to the lock he/she wants to defeat.

Once they get proficient with that lock, they sit down at a well lighted, comfortable bench and pretend to show how easy it is to pick the lock.
To defeat security, there's the '3T+2R' principle: Time, Tool, Training, Reliability & Repeatability. The reasons lock picking is not much of a concern for bicycle security are: it takes time to pick a lock one has never fooled with before in awkward position in poor lighting, it takes specialized tools (in the case of disc detainer locks, a very specialized and expensive tool), one has to train for some time to learn lock picking (A bike thief has the skills to pick an Abus X-Plus cylinder u-lock
and a Mul-T-Lock MT5+ padlock on a hardened chain? Riiiiight.), added to the fact that the
risk is the same whether the thief is successful or not.
Nope, not buying it. Bike thieves are going to snip, clip, shear, lever, bash, saw and jack locks, not pick them.
