I am more interested in who would design such fines. One of the great delusions we live in is that complex social problems have simple solutions.

As a practical example public train service in Germany was privatized some decades ago; obviously to guarantee quality the contract stipulate some quotas that need to be reached, one of these is that delays needs to be below a certain level; here comes a captcha, if a train is cancelled it does not count as a delay.

So the financial incentives are essentially to have little (but non zero) delays and cancel all trains with a above average delay.

You cannot game the system and expect the system is not going to game you.

Or better, are you going to be prepared for the consequence of a policy like the one you propose in practice?
