Local is a different story, anybody who drives with a foot alternatively buried on the accelerator and brake, is going to waste a heap of fuel.
When I hopped into this automatic Volvo, I was told that other drivers reckoned it went better if driven mamually. After driving it for the best part of 10,000km, I call BS. In manual I can make it burn more fuel and make more noise, but not go any quicker. Volvo have spent a fortune and put heaps of research into writing a programme for the transmission. Nobody will convince me that some hairy arsed truckie can do it better than a computer. Anyone who feels the need to save imaginary milliseconds, by using manual mode, is a stress induced heart attack, looking for somewhere to happen.
			
		 
	 
 Not only that, but it saves a fortune on clutch repairs. Scania was the same. And now, most big mobs put in AutoShift RoadRangers in the American stuff for the same reasons, and to prevent transmission failures from "driver abuse"
My old boss used to sook about us using cruise in his trucks because of consumption concerns. The R730 I drove could show litres/100 KM in the display, and I could get better results than him, when he used the pedal and I used cruise. 
Truck builders have emission targets to reach, just like cars. 
As for local, OptiCruise was a breath of fresh air. The loud pedal is part of the computer so pushing it through the floor only caused leg cramps. In a manual Double you'd change gears eight times and if you were more than three cars back you'd still miss the lights. The whole "auto" thing sort of encourages you to relax and let it happen.
