Like paul said, attitude and arrogance has alot to do with it. 
In our area we have large farms that operate alot of acres but would drop everything to come help a fellow farmer if he got stuck or had a fire or had an illness or stop by even on a busy day just to say hi and make time to serve on local community boards and churches.
And then we have farmers that farm similar amount of acres as the farmers in the paragraph above, but these guys run down the middle of the road with a 35' soybean platform on the combine and expect everyone to get out of their way, or pull out on the road with their grain cart ( not muddy ) to load trucks and expect traffic to stop and wait for them or pull huge chunks of mud on the road durring wet falls and not have the decency to try to scrape it off.  I kinda had to vent there didn't I ??
