Yeah, and a car with a knocking engine and multiple warning lights can still drive for thousands of miles before the engine explodes.

How many more alarms before you start taking the situation seriously? Complacency like what you suggest will be the order of the day right until things break, and then everyone will forget they thought this way and talk about how obvious it all was. Granted I don't have any solutions at hand, but better to start thinking about them now than later.
