BMW Driver Blocks Ambulance, Gets Out to Fight on the Highway

Where is the logic here? The BMW driver is upset that an ambulance slowed him down, so he decides to race ahead, block the ambulance, and then get out of his car to have an argument, which only makes him that much later! After a few harsh words (we assume) are exchanged in Russian, the driver climbs back in his douche-wagon, flips a quick bird, and then speeds away. This guy has just reinforced the entitled BMW driver stereotype.
