As a road cyclist commuter, I find that the most aggressive motorists tend to also be in larger vehicles. Whenever I'm taking the lane to attempt to prevent an unsafe pass, it's almost always the driver of a large truck that will still execute an unsafe pass anyway (forcing oncoming traffic to take evasive action) or will tailgate, rev their engine, yell out their window, and/or wiggle back and forth in apparent frustration and intent to intimidate me.
