Hi Ole_don:
___To me, risk is driving well above 70 miles per hour. Unfortunately, I see this every single day I am out on the highway. Me? Only if I really really need to:
A Hypermiling Angel guiding my way ... Even then, it is far beyond my normal risk level and is actually quite scary imho

I find a D-FAS in heavy traffic at slower speeds (or at least slowing) to be far less risky actually but that is just me?
___In regards to light throttle, I think we are headed toward common ground but anything near WOT? Not a chance in hell.
___Do not worry about staying on the right side of me in the least. We have some of the best back and forth discussions when in the head to heads here at GH
___Good Luck
