Our reader Dino Konrad has spotted another BMW test vehicle. He spotted this BMW 7 on April 1st, 2020 on the B11 between Wolfratshausen and Geretsried. As can be seen clearly, there are installations at the four corners of the vehicle, which are probably radar-equipped and the front ones seem to have cameras (the black holes). Also slightly above the front wheel there might be a camera, as well as in the middle of the rear window.
