I do drive conservatively on the highway. I accelerate rapidly to the speed of traffic (that 5.7 liter engine does a good job of it) then kick it into cruise control. In town is another story.
“I accelerate rapidly to the speed of traffic (that 5.7 liter engine does a good job of it) then kick it into cruise control.”
In the early 1980s BMW gave your driving method, as their recommendation for maximum mileage.
Accelerate quickly to desired speed, then hold steady.
