Your reply is a bit inconsistent. First, you ask if I ever go out with a bunch of bike friends as an objection to my argument. Then you change the premise to an unrelated point, moving it from 'a bunch' of friends to locking it to a single bicycle. You can't offer the latter in defense of the former, as they're two different arguments.

Now, there's a difference between locking a bike to one other bike, and stacking eight bikes and locking them all together. Sorry if I didn't make my feelings clear. There's just something about daisy-chaining eight bicycles that makes no sense to me. If I lock it to one bike, I can leave when I want. If I lock it and have others locked to mine, I can leave when they want. Unless of course I ride in a crew and then we all leave at the same time, which makes perfect sense and you're completely right, is not trendy in the least.
