Glad to know that an MOB on bikes has the automatice right of way..
The bikes were being operated in illegal fashion. the one that was tapped (he did not go down else the SUV would have rolled over him) did an volitional act to effect the SUV in some way and did not like the result he got.. well Drive by the law not the “hey there are a lot of us.. get out of way cager” rule and that will not happen
If it was even a maliciously intended encounter. I find a little respect and well wishing, even to a grody looking group of bikers, goes a long way. Locking horns over rights is sometimes not the right thing to do.
