pretty mutch agree with andy on this one, we all drive cars that are more than capable of over taking tractors quickly and safely, whether you choose to do so safely is a whole different argument as it wouldn't matter what you were passing.
What i think is more dangerous,( and illegal i think) is the amount of mud left on the road at tattie picking time by the huge trailers.
So can i have a shot of your combine as well
For what its worth, the worst thing on the road is Dundee taxi drivers.
