I don't think my Trackie tells me how many days I rode. 98% of my riding (so far) is commuting though. I am happy to say that only about a thousand miles this year were in a 4 wheel vehicle; the rest is my motorcycle or my bicycle. I definitely rode the bicycle more days to work, but that's only 18 - 34 miles per day, compared to a hundred per day when I drive or ride my Beemer. Nobody wants to count bus miles. :-(
