I'm unclear on what you are proposing. Do you mean that tires do not
blow off rims from brake heating? As a counterpoint, I have had two
of these occurrences and have witnessed many more. Beyond that, most
tandems use hub brakes because tire bow-off is such a problem for
them, having more mass and less wind drag than single bicycles and
only two rims for two people.

I think the management doesn't want the contention for road space
between bicycles and cars. I am aware of these problems locally
because there are a great many drivers who will not pass a bicyclist
climbing a grade on a curvy road even if the bicyclists rides outside
of the edge stripe on a paves highway. On an unpaved road this could
case traffic jams even with light auto traffic.
