If it was the tractors fault, I hope the family gets the farm and then some. You listed every excuse imaginable why the poor tractor operator had to kill this motorcyclist. Slow moving tractors kill people around here all the time and more times then not are at fault for creating a dangerous situation. I watch them turn across traffic, fail to stop at signs, and generally think they own the highways even though they pay nothing in fuel taxes that builds the roads.
Well SD I'm not sure how you know what fuel they run unless you watch them fill up - I run road taxed fuel in mine most of the time.
As to slow tractor killing this motorcycle operator, I'm at a loss how you get there. ( My GPS must be powered off)
Running stop signs? Don't know unless they can see all lanes going into the intersection.
It's all I can do to clear the quick light cycle on green sometimes, but I'm rowing as hard and fast as I can ...
I'll sit out a couple of red cycles sometimes until all traffic is clear for quite a ways - gives me a chance to wave while waiting.
AS to "getting the farm", only if the operating debt goes with it - I believe in all paying the fair share ...
