Think they must have been sued after some driver wasn't aware his signals were on, resulting in an accident. You could turn down the volume on earlier Cads. I artfully cut a piece of cling wrap and covered the speaker reducing the volume slightly and giving me moral satisfaction. Unfortunately, the car cleaners removed it and I'm not going to give them a hard time. Get used to it.
I live in Europe and such lawsuit is not possibleYou can't.
