“Blinker-Bimmel” at the Antara

Hello everybody, do you know that? If you start the turn signal too long at Antara (e.g. when you leave the highway with a longer exit) the “bimmel” (like the buckle warning) will eventually start … interestingly not in the city traffic. Does this have a special reason, or can this be deactivated? I find this extremely annoying. Thank you Greetings Anti-Driver
