as mossy john has clarified recently in this forum,
vehicular cyclists can and do use bike paths. they can use them safely. they can use them competantly.
vehicular cyclists can take advantage of bike specific engineering controls. vehicular cyclists can ride on bike paths.
and not as 'rolling pedestrians', as bicyclists on a path!
the disarming, misappropriated negativity surrounding bike infrastructure or use of bike specific infrastructure is sooooo misleading.
OF COURSE a vehicualr cyklist can ride on a side path!
