There seems to be some argument about how common this is for auto racing, but a similar scheme is the foundation of horse racing. Most thoroughbred races in USA (but essentially none of the ones you see on network TV) are "claiming" races. Any particular claiming race has a particular claiming price, e.g. $10,000. Before the race is run, any licensed trainer with sufficient money in his account for the deposit may claim any horse in the race. If the horse starts the race, it belongs to that trainer (or some other owner whom she or he represents) at the end of the race. That's true no matter how the horse performs or even if it survives the race. This complicated scheme is used in order to ensure relatively balanced fields, which is important for wagering. If favorites are too heavily favored, then no one will bet. So, you can enter a horse worth $25k in a $10k claiming race, and you'll have a great chance of winning, but you'll also have a great chance of selling your horse for much less than it's worth. The concept of "skin in the game" is fine, but I'm not sure this cascading infection scheme is the way to go. For one thing, physicians are rarely in charge of cleaning equipment. They have other expertise.
