The problem, Intheno, is twofold:
You can't currently read what's on the chips, so it doesn't matter if the fee to "call out" a team is $1 or $100,000, since you once the $whatever is paid, thee isn't anybody who can tell if the board is a cheater board or not.
Two, it's a bad analogy. In motor sports, you're dealing with a smaller, and relatively better funded, set of competitors. Where the cheats do the most damage is in Rookie/Novice, and those teams don't have $1,000 to spend even if they're 100% sure their opponents are cheating.
On top of that, a challenge-type rule is only a SUPPLEMENT to regular rules enforcement done by the league, not a substitute.
At the end of the day though, a challenge process doesn't really have anything to do with the rule at all - it's just a means of enforcement. Doesn't make any sense to talk about enforcement until you actually have enforcable rules in the first place.
We could ban eating syrup within 60 days of an event, and vacuum out the stomach contents of anyone playing to check for syrup if their opponent put up $1,000, but it wouldn't stop people from eating syrup in the 60 days before the event. Unless you can tell if people are cheating, no amount of penalty is going to do you any good.
