Yeah but 99% of thieves can't do that. If they could then they'd likely have a real job. Lots of locks are invulnerable to the picking, especially serious digital ones.
I’ve watched a bunch of lockpickinglawyer videos and there are locks he cannot pick at all, and locks which take a hell of a lot of punishment from a Ramset gun. It’s not out of the realm of possibility that you could build a bike lock which would effectively deter thieves. After all, it doesn’t have to be indestructible, it just has to convince the thief that your bike is not worth the time and risk of attracting attention.
One painful lesson I learned after having an expensive bike with an expensive lock stolen is that as you harden the lock at some point the weakest link shifts from being the lock to the thing the lock is attached to.
Get some brightly coloured spray-paint. Neon pink, gold or whatever. Paint the whole bike with it, obviously try not to get it in the mechanically sensitive parts but otherwise coat the whole thing. No-one is going to steal that, it will still ride just as well.
This is a little disingenuous. There exist locks that he cannot pick, but the vast majority of his uploads are three minutes or fewer and include a successful picking attempt. More on-topic for this thread, a common LPL theme is that bike lock chains are made of high-quality hard-to-cut material, but the lock cores are still often commodity parts which are picked open by standard techniques and tools.
I would say that much more important for discussing LPL is that he has immense real-world experience, equivalent to a master locksmith, and he builds his own picks. I am not the best lockpicker, but I bet that even I could open bike locks as quickly as he does, if only I had "the tool that [he] and BosnianBill made" in my fingers. Indeed, the community has talked quite a bit about the tool, and perhaps we'll get a 2020 gift in either a commercially-available version or public specifications for building them at home [0].
