• Unfortunately, to get the benefit of the slip steam, you gotta be pretty close to the back of the truck. If you have space for good reaction time, you’re probably too far back

      This is correct, especially at lower speeds. Greater fuel efficiency would come from lower wind and drivetrain resistance and use of a more efficient range of the motor’s powerband.

      Most vehicles are geared for optimal speed to fuel consumption around 55-65 mph (90-100 kph) not 70+ mph (110+ kph). So just going a bit under the speed limit can have a significant impact on fuel consumption.

      This has been tested. You still get a reasonable benefit 3 seconds behind; you get practically nothing 6 seconds behind
