I've been cycling to and from work for a year now and exhaust fumes have never been an issue, but last night the driver of a red something or other really had to get in front of me just in time to join the queue of traffic to the roundabout. I then had to sit behind him breathing in noxious fumes as the exhaust belched out black smoke. I kind of hope that means his car is about to break down. Not content with pulling in front of me, he then shot off at the RAB right into the path of an oncoming car. I kind of hope that means he'll crash soon too.
