As for the question, I guess it's an attitude thing, and I'm very much guessing here, but when I commute on the bike it's more about just getting to where I need to be as quickly and with as little fuss as possible; whereas when I'm out at the weekend I'm more likely to indulge in a spot of "wonder if I can get my knee down round that bend" - even if I'm doing the same roads as I would do during the week.
