Interestingly it is often possible to put two bicyclists on
most roads, with a motorcycle in between them.

*If* it is done carefully, with near zero relative velocity.

The real danger, and I'm sure Jim R. has been there,
is two motorcycles riding a safe distance between
each other and passing a bicyclist. The bicyclist
yields for the motorcycles, sees the first one
pass then unaware, swings out in front of the second.
