Some of the electric cars have artificial noise that is far, far louder than any combustion engine. There is one that sounds like a spaceship hum from the movies that I can hear in my apartment despite not reallly hearing any ICE engines other than delivery trucks.

Whoever designed that one went overboard.

they aren't though... all i can hear when they are on is the loud whirrring of the electronic motors. i like of hate it tbh, regular cars aren't as loud to me.
