2. Is it advantageous to drive in the low pressure zone on the side of a truck - mileage wise. If you don't know what I mean, the next time you're on the freeway and you're passing a semi truck, notice that as you come up the side of the semi truck there's a tendency for your vehicle to be pulled in towards the truck - and as you get to the front of the truck, the air being pushed out of the way of the truck will tend to push your car away from the truck.
The lighter the car you drive will make this more apparent, as will you and the truck traveling at higher speeds.

1) i say yes to the retaining wall if the highway is not divided as in the traffic is immediately on the other side of the wall
2) The only time i pass a semi is when they just pull out onto the same road and their traveling much slower then their speed limit which im already going so that affect is unseen

but i would say yes because the air is being split off at an angle which would help
