Drive like a dick season has arrived

What is it about autumn that makes people drive like dicks?  This morning, I've seen a bloke in a van, holding his phone in his left hand, placed against his right ear, whilst trying to do a U-turn on a busy road.  I was cut up by a bimbo, who then went straight through two red lights, and then had to wait whilst someone driving on the wrong side of the road made a decision whether to get on the right side of the road, or just stop in the middle of the road.  Then there's the plethora of people who don't know what a handbrake is for, and just sit there either blinding you with their brake lights, or holding it on the clutch crawling forwards and slipping backwards.  I hate this time of year on the roads.
