DISCLAIMER.......THIS IS ILLEGAL (AND PROBABLY FATTENING) IN MOST STATES......UNLESS YOU HAVE FAST REFLEXES AND ARE VERY AWAKE I DON'T RECOMMEND IT.....IN FACT, I DON'T RECOMMEND IT AT ALL.....EVER.
That said.....
Growing up in the old country (70's) I drove one of these:
27 horsepower...... So, my commute was about 45 minutes every morning. The routine was to set an alarm early, and listen to the weather man to get wind direction and velocity..... You see, a headwind would make the commute an easy 60 minutes, as the top speed would decrease from a blistering 65-70 to 50.... or worse.
What we learnt to do in bad headwinds was to snuggle up behind a big truck and to just stick with them like a remora. Often the truck drivers would know you were there and would drive accordingly, leaving you room to stay put.
So...... last night we had another 54 miles to go to the next Flying J, and according to the fuel range we had about 50 miles left in the tank.....
That's too close. So, as it was the middle of the night and the road was about empty I tucked in behind an 18 doing 64-65 and stayed there. How close is close? Well, 20-30 feet..... Cranked the trailer brakes up to 7 and figured that he wouldn't be able to stop any faster than I was. And, I sat up and had both hands on the wheel and one foot a half inch above the brakes.
So I reset the MPG and went from 10-11 to.......16!!!!!!!!!!!!! And yes, we made the Flying J with room to spare.
So, if you're ever in a pinch.....it DOES work.
OK, bring on the lynch mob.....
