If it takes me 2 minutes to walk over that bridge (say), unless I'm
injured I know it will always take that.

It's much more than 2 minutes.

That's irrelevant to my point. My point was that however long it
takes, it is a predictable amount of time that will always be the same,
unlike a transit train.
