Most cycle commuters I've seen in Belgium and Holland are of the pootle variety on upright bikes and are in normal clothes riding quite short distances into work as cities are smaller.
A significant proportion of London cycle commuters are lycra clad speedsters riding longer distances on their commute, hence discussions here about showering facilities etc at work. Many (see discussions on here) seem to use commuting as training.
Yes exactly my experience as well. In Holland the Lycra cyclists are out at the weekend especially Sunday rest of week mainly see the "pootlers"
