Cruise control is a system that automatically controls the speed of a motor vehicle. It is typically used on highways and other roads where the speed limit is relatively constant. There is some debate about whether cruise control uses more or less gas than manually controlling the speed of the vehicle.
One of the main benefits of cruise control is that it can help to improve fuel economy. This is because cruise control can maintain a constant speed, which is more efficient than constantly speeding up and slowing down. Additionally, cruise control can help to reduce driver fatigue, which can also lead to improved fuel economy.
However, there are also some potential drawbacks to using cruise control. One is that it can be less responsive than a human driver, which can be dangerous in certain situations. Additionally, cruise control can sometimes cause the vehicle to speed up or slow down unintentionally, which can also be dangerous.
Overall, cruise control can be a useful tool for improving fuel economy and reducing driver fatigue. However, it is important to be aware of the potential drawbacks and to use cruise control only in situations where it is safe to do so.

Fuel economy
Cruise control is a system that automatically controls the speed of a motor vehicle. It is typically used on highways and other roads where the speed limit is relatively constant. There is some debate about whether cruise control uses more or less gas than manually controlling the speed of the vehicle.
One of the main benefits of cruise control is that it can help to improve fuel economy. This is because cruise control can maintain a constant speed, which is more efficient than constantly speeding up and slowing down. Additionally, cruise control can help to reduce driver fatigue, which can also lead to improved fuel economy.
For example, a study by the U.S. Department of Energy found that cruise control can improve fuel economy by up to 14% on highways. This is because cruise control can help to maintain a constant speed, which reduces the amount of fuel that is used to accelerate and decelerate the vehicle.
Overall, cruise control can be a useful tool for improving fuel economy and reducing driver fatigue. However, it is important to be aware of the potential drawbacks and to use cruise control only in situations where it is safe to do so.
Driver fatigue
Driver fatigue is a serious problem that can lead to accidents, injuries, and even death. Cruise control can help to reduce driver fatigue by maintaining a constant speed, which allows the driver to relax and focus on the road.
- Reduced need for acceleration and deceleration: Cruise control eliminates the need for the driver to constantly adjust their speed, which can reduce fatigue.
- Improved posture and ergonomics: Cruise control can help the driver to maintain a more relaxed and comfortable posture, which can reduce fatigue.
- Reduced mental workload: Cruise control can reduce the mental workload on the driver, which can help to improve alertness and reduce fatigue.
- Increased safety: Cruise control can help to improve safety by reducing the risk of accidents caused by driver fatigue.
Overall, cruise control can be a useful tool for reducing driver fatigue and improving fuel economy. However, it is important to use cruise control only in situations where it is safe to do so.
Safety
While cruise control can be a useful tool for improving fuel economy and reducing driver fatigue, it is important to be aware of its potential drawbacks, including its reduced responsiveness compared to a human driver. This can be especially dangerous in certain situations, such as:
- Sudden stops: Cruise control can be slow to react to sudden stops, which can increase the risk of a rear-end collision.
- Curves and bends: Cruise control may not be able to maintain a safe speed on curves and bends, which can lead to the vehicle drifting out of its lane.
- Adverse weather conditions: Cruise control can be less effective in adverse weather conditions, such as rain, snow, and ice, which can make it difficult to maintain a safe speed.
It is important to be aware of the limitations of cruise control and to use it only in situations where it is safe to do so. Drivers should always be prepared to take over control of the vehicle if necessary.
Unintentional acceleration/deceleration
Unintentional acceleration/deceleration is a serious problem that can lead to accidents, injuries, and even death. Cruise control can sometimes cause the vehicle to speed up or slow down unintentionally, which can be especially dangerous in certain situations, such as when driving in traffic or on slippery roads.
There are a number of factors that can contribute to unintentional acceleration/deceleration, including:
- Malfunctioning cruise control system: The cruise control system may malfunction and cause the vehicle to speed up or slow down unintentionally.
- Driver error: The driver may accidentally activate the cruise control system or set the speed too high.
- Environmental factors: Certain environmental factors, such as rain, snow, and ice, can affect the performance of the cruise control system and increase the risk of unintentional acceleration/deceleration.
If you experience unintentional acceleration/deceleration while using cruise control, you should take the following steps:
- Turn off the cruise control system: The first step is to turn off the cruise control system. This can be done by pressing the "cancel" button on the steering wheel or by braking.
- Apply the brakes: If the vehicle is accelerating unintentionally, you should apply the brakes to slow down the vehicle.
- Steer the vehicle: If the vehicle is decelerating unintentionally, you should steer the vehicle to avoid crashing into other vehicles or objects.
Unintentional acceleration/deceleration is a serious problem that can lead to accidents, injuries, and even death. It is important to be aware of the risks associated with using cruise control and to take steps to avoid unintentional acceleration/deceleration.
Conditions
The impact of cruise control on fuel economy can vary depending on a number of factors, including road conditions, traffic, and vehicle type.
- Road conditions: Cruise control is most effective on flat, straight roads. On hilly roads, cruise control can use more gas because the engine has to work harder to maintain a constant speed.
- Traffic: Cruise control is less effective in stop-and-go traffic. When the car is constantly slowing down and speeding up, cruise control has to work harder to maintain a constant speed, which can use more gas.
- Vehicle type: Smaller, more fuel-efficient vehicles will typically see a greater improvement in fuel economy from using cruise control than larger, less fuel-efficient vehicles.
It is important to be aware of these factors when using cruise control. If you are driving in hilly or stop-and-go traffic, you may want to turn off cruise control to save gas.
Overall, cruise control can be a useful tool for improving fuel economy, but it is important to use it wisely. By understanding the factors that can affect the impact of cruise control on fuel economy, you can make the most of this feature.
