I think this is a really bad idea unless paired with some regime that penalizes inappropiate use of alarms - and most societies don't treat noise pollution as a real problem. For example, people honk all the time even when there are no safety issues. Or have misconfigured home/car alarms. Outlawing using ANC for blocking "fake alarms" only makes the problem worse.

Why do you think that's the case? Many companies are a good investment, while they still provide affordable products. Something can be cheap in an absolute sense, while still providing a good return on investment.

Could you have instead changed your code? It's generally best to assume that it's not possible to delete secrets once they are shared (after all, in worst case, the driver could have just remembered the code from the previous visit)

Is there anything that stops patients from lying that they are in a different state (just temporarily)?
