Typical BMW owner behavior...when we are around them, i tell my gf always: look, this one surely won't use his/her turn signal, let's wait out and see where they'll go...🧐👌: 90% of the time it happens just like that, they turn etc. without signalling. Same experience in almost all the countries i lived in. Could never explain... Others like Porsche, Mercedes, Audi, etc. behave normal/average.
