For most drivers, using cruise control on the highway at 80 km/h can reduce fuel consumption by about 20 per cent. For drivers who find difficulty in maintaining a steady speed and frequently experience big fluctuations, using cruise control can cut fuel use by over 40 per cent. Cruise control work with a manual transmission just the same way it does with an automatic. Drivers set their cruising speed with a button press, and the system works the throttle automatically to maintain the desired cruising speed as evenly as possible.
Is adaptive cruise control worth it?
Cruise control bypasses the manual throttle adjustment and directly communicates with an actuator. The automated system can also maintain unsafe speeds, even on ice or steep inclines. Plus, most vehicle manufacturers caution against using cruise control on wet pavement, and especially on ice or snow. Of course, there are many nuances to driving, and that includes the use of automatic speed controls. Here we’ll explain in more detail exactly why cruise control is safe in some situations and not others.
Is cruise control safe?
As per initial reports, the cruise control feature tends to improve your car’s current fuel economy by at least 10-15% on highways. When you use your car’s cruise control under normal conditions for which it was designed, it will not be bad for your engine, transmission, brakes, or other parts of your car. When you are driving on a hill, we recommend you use your car’s brakes and accelerator to manually let you control your speed. Keeping cruise control engaged is only beneficial when on long drives on a straight road with less traffic. Despite this, remember that cruise control is not a self-driving feature; you have to be still attentive to ensure your safety and others on the road.
Inefficiency in city driving
Cruise control is a smart feature in modern cars that lets you set a specific speed your car will maintain without you having to keep your foot on the gas pedal. It’s sort of like setting a pace for a marathon, so you don’t have to think about it constantly. According to the Department of Energy, your gas mileage drops quickly once your car reaches over 50 mph. This is because braking and accelerating too quickly while driving wastes a lot of fuel in the long run. Some people also develop a lead foot when caught in heavy traffic.

Most models rely on engine braking—downshifting to reduce speed—when going downhill. Nor does the automatic braking some newer vehicles use to decrease momentum. Any cruise control feature can increase fuel efficiency by a considerable amount of 10-15% on highway speeds.
Is It Ok To Use Cruise Control All The Time?
Laser and other technology may not work correctly in the fog, for example. To maintain your driving conditions in dense traffic, you must adapt your speed manually. You should be especially careful about construction zones, rush hour and slow traffic areas. Remember, adaptive cruise control cannot save you from all types of traffic-related dangers. A common misconception is that cruise control is bad for your car. The top brands install this feature on new cars because they know that it can make a car last longer.
Adaptive Cruise Control: The Next Generation
Luxury automakers such as Tesla and Audi are implementing the newest rendition of cruise control on their latest vehicle models – Semi-autonomous Cruise Control. It works largely the same as adaptive cruise control, but assists drivers with lane guidance and steering. There are several variations of semi-autonomous cruise control that include additional convenience features for the driver. Additionally, while Adaptive Cruise Control technology is pretty smart, it’s not perfect. It might not react to stopped vehicles or non-moving objects like a manual driver would. In mechanical terms, the car runs on constant RPMs, and this signifies less consumption of fuel.
As autonomous vehicles become more sophisticated, cruise control technology is evolving to support higher levels of automation. Now, if conventional cruise control is your old reliable friend, then Adaptive Cruise Control (ACC) is like that friend's tech-savvy younger cousin. ACC isn't just maintaining your set speed, it's also keeping an eye on the car in front of you. If that car slows down, ACC slows your car down to keep a safe distance. However, MotorTrend cautions that you should never use cruise control in heavy rain or snowy weather.
Types of Cruise Control Systems

No, be it any type of fuel your car uses like diesel, petrol, or gas, the cruise control enhances fuel efficiency, which isn’t possible without the feature. Due to this feature, the engine keeps the car constantly running without indulging in additional work. As said above, the cruise control’s primary purpose is to lock the accelerometer at a specific speed and allow you to take your foot off the pedal. Talking about the various advantages the cruise control feature offers to the drivers on long and straight trips with minimal to no need to change gears, cruise control is a boon.
Such conditions can lead drivers to feel claustrophobic and irritated, causing aggressive driving. Most vehicle manufacturers caution against drivers using the function on windy roads or when going uphill. It’s another case of the cruise control only adapting to specific scenarios; it can’t see the curves ahead or the sharp decrease in elevation.
This feature reduces your tendency to speed, which ensures safety. You can drive safely because there is not much risk of an accident. This is really a good feature for people with lead foot syndrome.
The risk of falling asleep behind the wheel and causing an accident is too high. Don’t use your cruise control when there are a lot of cars on the road. This makes it too hard for you to keep up with the flow of traffic.
Driving long distances usually requires that you keep one foot on the gas pedal at all times. It’s often easy to get caught up in the flow of traffic and drive a little faster than you would like, which some refer to as having a lead foot. Cruise control works well when you have a straight road ahead of you and can keep an eye on traffic. This system has a cable that runs from the steering column to the vehicle’s actuator. You press a button or turn the knob to the on position and pick the speed you want to use.
