I live and ride in So. Cal. In over 30 years of riding I’ve never had an issue with a BMW or. Benz driver.
A moron in a green beamer near the I 10 interchange that is the San Bernardino/Loma Linda border insisted that I ride to the right edge of the freeway entrance lane instead of the right most straight thru lane. It started with me waiting behind a dozen cars at a light and ended with me taking sanctuary behind a power pole. No damage to my tandem. My left pedal did have a little green paint on it from the beamer. Three other beamers have done brake checks to me in the same area. Where I live in the high dessert I have had hardly a horn honk in almost 5 years.
