“Guess you didn’t see the clip where he drove over a biker - which precipitated the other bikers chasing him down.”
Guess you didn’t see the clip where the biker was riding next to the SUV driver in the same lane then cut him off and hit his brakes to cause the accident.
You need to look again. Your description of events comes from halfassed media explanations by people who are not good at geometry, bikes, cars, or anything else. For instance how and who on a bike would try to cut off a full-sized SUV? The SUV REAR-ENDED the first bike.
