For one, when and where this was the case, it was probably once a year or so.* Not daily or weekly.

Furthermore, the "voluntarily" bit plays a big role as well. If I were to go to a big festival (as you can guess, I wouldn't), then I guess I would be fine with the people. But that's not the same as commuting IMHO, where I'm together with lots of people involuntarily.

* it's an interesting topic actually, so if you have any sources, I'd like to read them.
