I don't know what happens when people get behind the wheel or handlebars (as the case may be), but they sometimes get transformed into monsters. Over-reacting, and with violence, to any perceived provocation by other road users.
Is it the stress of modern life in general or the stress of the daily commute in particular or is it that these are simply dysfunctional people who think they can get away with violence because they happen to be already sitting in their getaway vehicle?
