I've noticed that car alarms that go off for no good reason seem to be back. Those used to be a thing, but they'd mostly disappeared. But I keep hearing them in parking lots, with nobody anywhere near the car. At least they shut off after a while. That was legislated back in the 1980s.

Sometimes it can be a genuine mistake.

I was in my garage with my keys in my back pocket, checking the tire pressure on my truck, when it started honking at me. My butt triggered the panic button.

I have acute hearing. That was painful and hardly deliberate!

So in the 2000s, this was fairly common in India. Then one day a installation mechanic told me the sensor had various calibration settings. You could get the trigger to be as sensitive as you wanted.

At times a rodent or a crow could trigger the alarm.
