On several occasions I have been behind a Chevrolet Corvette which was stuck behind a tractor because the Corvette driver couldn't see to overtake. Road accident rates around US airbases are quite a lot higher than the national average.The first 30 years of my life existed in the UK, and from when I can remember, there has been US air bases there, a couple that were near to where I lived, I knew and partied with many of the family's that lived off-base.
They of course brought their US auto's with them, which at that time were of a size that just about took up the whole of small English country roads.
During that time, I never heard of any of them reported driving on the wrong side or any accidents due to it.
I had the same driving experience when I came to Canada and soon got the hang of it. Driving on the right, that is.
