that guy was an out of control dick. but, as i have become older and more boringer, i have learned something: generally, it is best to avoid creating confrontations. especially when one half of that confrontation is some horses ass driving a 2000 lb. lethal weapon with an engine in it.
back before i realized how much it totally fucking sucks, i used to occasionally ride with critical mass. this is where i learned that, 1. blocking the road pisses people off like nothing else and 2. people driving cars will actually crash into you on purpose if you make their ride even a few minutes longer than it might otherwise have been.
