Thing is, (and also in no way am I endorsing Litelok) in the real world it wouldn't be so easy to get through that in 16 seconds, not many thieves (some do I concede) would want to draw so much attention to themselves in broad daylight in town with a big pair of bolt cutters, then you have the matter of the lock not being as easy to access with the cutters when it is attached to a motorbike, if the lock is raised off the ground it is a lot harder when the thief can't use the ground as an anchor to operate the bolt cutter.
At the end of the day, any lock is just a deterrent, the more layers of security the better chance you have of thieves stealing someone elses bike and not yours.
