I know they are busy and have a job to do, but farmers and their massive vehicles. This morning I was heading to work and passed a big tractor with trailer coming the other way. This was on a slight right curve in the road. Suddenly there was some sort of massive combine type of machine, with tank tracks. It filled the opposite carriageway and was around a third into mine. We both stopped and I had to squeeze through, passenger wing mirror scratched up in the hedgerow, drivers mirror about an inch from the tank.
Firstly, why do they always seem to get on the road during rush hour?
Secondly, surely that vehicle should have some sort of vehicular escort? Damn dangerous. 
Like the big tractor towing a trailer that preceeded it?
