flynjay: I have similar thoughts to you. Stealing from someone's business is wrong, but these guys really do have a smart way of going about it. You should see London traffic too. The only things that flow through the city are motorcycles and mopeds. The UK police have some very skilled motorcycle riders, but I doubt even they could get to the scene of the crime within 2 minutes of it being reported and then identify and chase all 3 bikes.
We do have a ton of cameras here. I have wondered if they could track them all the way back to where they dumped the bikes. Presumably the thieves have thought about that too and chosen a black spot where there aren't cameras.
