I did it once about a decade ago when I busted the chain on my brifter road bike (before my CV awakening) while wearing bike shoes with speed-play cleats, so walking the bike was actually waddling. About 1 mile from home I went by a "free bike" (A Schwinn Mesa runner with Free Sign) ) that was in need of TLC but rideable. I took off my bike shoes and strapped them to the rack on the MTB and ghost rode the last mile in stocking feet, in addition to the ghost ride I got some ghost shifting from the rusty dry MTB drive train. I stuck to back roads and probably wouldn't have done it but for the seeming necessity at the time. That free bike later became a project I built for my then (now ex) wife. As has been said above I survived but probably wouldn't do it again.

I didn't know about drive side shots back then!
