I use it religiously, mostly because my commute is long and I believe it helps with gas mileage.

So tell me...any good reasons NOT to use it?

The elevation change from 31' to 115' on my way to work is a killer! jk Most days I only drive within an 8 mile radius of my home. It's pretty flat, but is mostly surface streets. Not ideal conditions for cruise control. When I take a road trip, I use cruise control when I think about it.

RIVERRISING writes (about cruise control): NEVER. sucks fuel.
_____
Cruise control will save fuel if it's used under the conditions where it performs best: flat roads and low traffic. The opposite is also true.

Newer adaptive systems will increase fuel savings when they take advantage of traffic and changing elevation.

On flat and level a CC will return best MPG for a given speed. But not on hills. Is better to let the vehicle speed up 5 to 8 MPH on the way down and then hold the throttle fixed on the way up than to close it on the way down and floor it on the way up.

Ah, the advantage of sufficient torque so that down shifting isn't an issue. Too much weight for you engine is the issue not the cruise control.

Up hills is right, cruise would downshift causing your car to pump extra gas not needed. Good call out. :)

Borsht is right. If you are driving hills you are better off not using the cruise.

One can get better gas mileage by not using it, if he is conscious of hills.
To maximize your fuel economy, lose about 5MPH going up hill. Pick it up going down hill. this is free energy. The cruise control will maintain your speed, shift down to higher engine rpm, wasting gas.

I don't think there is a single reason not to use it.

And a interesting fact for icy / bad weather - if your car tells outside temperature and usually beeps when it is below freezing, thats not just to say "hey it's cold". It reports the signal to your sensor chip for your transmission and anti-lock breaks usually controlled by traction control (some cars it's a little green light for the second or two when it is used)

Basically cars are remarkably intelligent - when you hit resume on your cruise and there is ice on the road and the tire goes to slip it transfers the power to the tire with traction and goes back and forth and will allow the safest way to increase speed.

"The Test" (disclaimer, I do not recommend anyone to do this ever!) If you go to an icy large parking lot with no cars. 90% of cars have button to turn off traction control (probably a button you have never pressed) turn off you traction control and floor it. if you really want to "test other smart systems your car has" pump the brake to stop as older cars it was required.

The second part is make sure your traction control is on, Floor the gas - your actual time to the determined "finish line" will be faster with traction control on. When breaking you can apply steady even pressure all the way to the floor if you want and you will notice a much faster stopping time as well.

All of this was to demonstrate our cars know more about driving in such conditions than we do. disclaimer* but driving with your cruise on can actually be much safer.... Plus increase gas mileage.... :-)

I'm a tech junky and it is shown and noted that by 2020 computers will become a much superior "brain" than any of us. NO TERMINATOR event will happen. It just means we can tell us what we are trying to accomplish and it can solve it well before man. England has cars currently on their roads that drive themselves. This began two years ago.

Trust your car - it's smarter than you think.

I almost always use it on interstate type driving. Rarely on local roads. I'm planning a 1400 mile round trip drive this month. About 80% should be on Cruise Control weather permitting.

to p*** off the cars behind you. Speed up, slow down, speed up. slow down. That's what you do when you don't use it. Almost ALL of you.

Cruise control increases gas mileage as most drivers are prone to be distracted, phone, radio, others (talking), anything outside the car. With these distraction, statistically drivers fluctuate their speed much more often and open the fuel intake in the carburetor or fuel injection to react to you changes in pressure. Vehicles since 2000 and slightly before are "smart' cars. That means based on the key - different drivers - The car learns your typical driving habits and mimics your usual changes. This will then change the way cruise control acts which is why those who haven't used it because of more agressive driving habits will not notice a difference in mileage. Those who trust the car and it's natural settings will see 3 to 5 MPG difference with cruise on. This is also a bell curve depending on the type of vehicle you have. The larger, gas guzzlers would notice the biggest difference. In my lifted Diesel guzzling Dodge I gain 6-8 MPG.

However - your A/C will effect it, but only about 1 MPG or less.

In slower traffic under 50 mph.where most drivers stay 50-100 ft from each other,exceptions then,150-200 ft.maybe cruise can bring about a rear-ender.The slightest distraction,even with the brake pedel releasing the C.. C.. control can often be too late comming about.

Cruise is handy when used proper,not for being lazy/krazy/silly/dilly..LOL!

The cruise control feature as it is executed on most cars is a dumb device that requires as much driver attention as just driving the car. In hilly terrain, it is better to just leave it off because it is good to increase speed on downhill runs to build momentum for the climb ahead. In busy traffic it is just better to leave it off because people are constantly switching lanes and sometimes very abruptly. There have been very few instances where I found it useful because road and traffic conditions change so quickly.

With the adaptive cruise controls starting to become available, my opinion could change.

Cruise can't look at the road and anticipate events that will happen, and it certainly can't make good judgements when going over a hill. A human being can. Cruise is great, but I turn it off temporarily in certain situations. And in snow and ice, I don't bother turning it on.

I'm uneasy using cruise control because my foot is too far away from the brake pedal. I ususally put my foot flat on the floor or elsewhere. Kinda dangerous when you think about it.

When going downhill - cruise control will sometimes apply the brakes to keep your car from going too fast - using the brakes to maintain a fix speed is not as fuel efficient as allowing the car to gain speed on the downhill and allowing aerodynamic drag and gravity and road surface friction to naturally slow down the car.
