Segway Petanque - Why Not?

As an interesting variation to petanque, we had our first player on a segway try the game out.  The rules of petanque permit (kinda) a segway player to participate.  As long as one wheel is in the circle...   I'm not sure what advantage segway players would have, however, because the machine keeps wanting to "right itself" which throws the aim completely off for a player.
