The constant roar of traffic makes many a city center noisy. Then you drive home to your quiet suburb, where traffic is less of a problem… but cars still make their presence known there. Apart from the infamy of car alarms , each time a neighbor parks a car, or gets into one, you hear the multiple bleeps of the remote controlled electric locking system.
Let’s avoid the question of why a car needs to beep when you lock or unlock it (surely blinking the lights would be informative enough); but if they gotta beep, at least the designers should try to make the beeps quiet! In reality some cars are considerate, and give off pleasant, melodious peals of unnecessary sound; but there are many that squawk like a hen that had its tail stepped on. If you have a neighbor that works late night shifts, or otherwise needs to drive when others are asleep, this can become a real nuisance.
Hear that, Detroit?
