The modern technology with the worst signal-to-noise ratio is …

…the car alarm.

When one goes off, the community’s reaction is not “Catch the thief!” but “Find the car owner so s/he can turn off the @!@#ing car alarm.” At least in the communities I’ve lived in. (Note: I am a privileged white man.)

The signal-to-noise ratio sucks for car alarms in every direction. First, it is a signal to the car owner that is blasted to an entire neighborhood that’s trying to do something else. Second, it’s almost always a false alarm. (See note above.) Third, because it’s almost always a false alarm, it’s an astoundingly ineffective true alarm. The signal becomes noise.

Is there any modern technology with a worse signal-to-noise ratio?
