[ppvbxkky] Bicycling without performance enhancing drugs

Consider a bicycle race in which the organizer provides no infrastructure for measuring times.  Each racer is independently responsible for measuring and reporting his or her own time.

Then, when a racer reports a time, the listener must decide whether to trust the racer.  We force the issue of trust to be central, bringing in, of course, whether also to trust that the racer is not cheating by using performance enhancing drugs.  You can cheat either way; the organizers are not stopping you.

Voluntary signaling mechanisms to cause trust will form, as predicted by the game theory of imperfect information games.

Vaguely similar previous idea, permitting everything.
