When I drive on a highway and I use the cruise control, does the car consume more fuel, less fuel or about the same?
Assuming fuel consumption is compared to driving at the same speed for the same distance just without the cruise control. Theoretically, you should get both the same.

It depends on the road you're on. If it's flat, use the cruise control and you'll save a lot of fuel (up to 10%!). If it's a mountain road, don't use it.
Assuming a long flat road, you will get a lot better mileage because by going at a steady speed you avoid constant acceleration. When not using cruise control one cannot help but constantly accelerating and decelerating so as to hurt fuel economy.
Actually it saves ampul amounts of fuel while on cruise control more then u might think see when u set the cruise control the truck is automaticly " sorry about my spelling" lol. adjusting itself to the speed and contour alone meaning its self shifting and thinking and when it feeds on its own then its at the most non stressed point of opperating so most deffinetly a fuel saver lol

What is the law on cruise control? Is it permitted to use on all roads, such as urban areas with 30 mph limits
You only live once go for it
less fuel. bacause the throttle mostly stays in one place! stop and go and city driving kills gas milage.
