UT - yes, yes, no and no
it is incredibly unsafe.

When a driver drafts my truck, his/her eyes are naturally drawn to my taillights to the exclusion of all else. With their eyes totally focused on my rear lights, drivers tend to miss things like signs, turn signals, exits, even other vehicles.

And the fuel savings aren't enough to matter on a per-tankful basis. I should post a picture of what happens to a car that gets squished under a truck back there, but no one would look at it.

Bottom line, please stay back 50 feet, or one trailer length to give yourself enough time to react to anything that might happen. The air back that far is still disturbed enough to ease the power burden on your engine and fuel economy. Tailgating like that is a primary offense in many jurisdictions so I may also be saving you a traffic ticket. I *am* saving your life!
