I might have also said that they tend to "

*end up* close to where they started."

Yes, it seems that one might be able to make conclusions based only on how far away one traveled from their starting location.

Probably. It would be an interesting thing to simulate.

The distribution of race scores might also be an interesting data set for analysis. Might the outcome resemble the results of something like a

Galton box and have a predictable distribution? Could race officials thereby detect cheating by a statistical hypothesis test of the distribution of scores? For example, one might expect that ~1/2 the cars end up toward the right of their original location, and ~1/2 end up toward the left. This would not necessarily identify individual cheaters, but it might suggest anomalous activity within the population of race outcomes, say, if the population of scores were highly asymmetrical.
