Car locks that trigger the horn and lights. Whatever asshole engineer decided that was a good idea (instead of just making the key fob blink or something) clearly has never had neighbors.
The keyfob doesn't actually know if the car received the signal or not, which is why the car has to react in some way.
The keyfob already has two way communication for the challenge-response protocol, so it is perfectly possible for the car to send a signal back saying it was actioned.
Huh, TIL. I didn't know this!
Or the stupidly sensitive car alarms that react to the slightest movement (ahem BWM and Audi and Mercedes)
Everytime I take a ferry those vehicles are blaring their alarms for the entire trip and they need to announce on the P.A for the owner to come back and turn the alarm off.
Life pro tip, if you leave your car on the ferry, don't turn your alarm on!
This can be turned off on every car I have ever interacted with by holding specific buttons on the key fob
You and I may be the only two people in the world who do that.
Most cars I've experienced announce it only visually, using the blinkers.
It doesn't trigger the horn on UK cars, which I definitely appreciate. Although it was amusing to watch my partner jump every time I locked our hire car in the USA, the noise pollution is unnecessary.
Ha, I was thinking that I never recalled the sound going off on any car in the UK, but regularly and obnoxiously goes off in China. But nobody gives a shit about noise in China.
