Just a whinge

Ok, so i was ridin home from work yesterday and i was coming up to a round-a-bout when a guy in a 4wd towing a trailer came from the left and cut me off. And i mean to the point where i had to jump on the brakes HARD. He didnt even look to see if there was anything coming. Then he proceeded to drive at 10kph under the speed limit till he turned into a driveway about 500m or so up the road. Dumb shit.
