Is automatic emergency braking worth it?
Automatic Emergency Braking (AEB) is a safety feature that has been gaining popularity in modern vehicles. Designed to prevent or mitigate collisions, AEB systems use sensors to detect potential obstacles and apply the brakes if the driver fails to respond in time. But is this technology worth the investment? As an experienced auto service provider, I’ll break down the benefits, potential drawbacks, and considerations to help you decide.
What Is Automatic Emergency Braking?
AEB is an advanced driver-assistance system (ADAS) that uses cameras, radar, or other sensors to monitor the road ahead. If the system detects an imminent collision with another vehicle, pedestrian, or object, it automatically applies the brakes to reduce the severity of the impact or avoid it altogether. Many manufacturers now include AEB as a standard or optional feature in their vehicles.
The Benefits of Automatic Emergency Braking
There are several reasons why AEB is considered a valuable safety feature:
- Reduced Risk of Collisions: AEB can significantly lower the chances of rear-end collisions by reacting faster than a human driver in emergency situations.
- Enhanced Pedestrian Safety: Some AEB systems are designed to detect pedestrians and cyclists, providing an added layer of protection for vulnerable road users.
- Lower Repair Costs: By preventing or minimizing accidents, AEB can save you money on costly repairs and insurance claims.
- Insurance Discounts: Many insurance companies offer discounts for vehicles equipped with AEB, as it reduces the likelihood of accidents.
Potential Drawbacks to Consider
While AEB offers numerous advantages, it’s not without its limitations:
- False Alarms: Some systems may activate unnecessarily, causing inconvenience or even creating a hazard if the brakes are applied unexpectedly.
- Cost: Vehicles equipped with AEB may have a higher upfront cost, and repairs to the system can be expensive if it malfunctions.
- Over-Reliance: Drivers may become overly dependent on AEB, potentially leading to complacency behind the wheel.
Is AEB Worth It for You?
Whether AEB is worth it depends on your priorities and driving habits. If safety is your top concern, AEB is undoubtedly a valuable feature that can provide peace of mind and potentially save lives. For families, frequent commuters, or those driving in high-traffic areas, the benefits often outweigh the costs.
However, if you’re on a tight budget or primarily drive in low-risk environments, you may find it less essential. It’s also important to remember that no technology can replace attentive and responsible driving.
Conclusion
Automatic Emergency Braking is a game-changing technology that has the potential to make our roads safer. While it may not be perfect, its ability to prevent accidents and reduce injuries makes it a worthwhile consideration for many drivers.

Frequently Asked Questions
What is the difference between brake assist and automatic emergency braking?
Where do AEB and BAS differ? AEB doesn't require the driver's foot pedal action to initiate the braking. It applies the brakes automatically. It's important to note this difference because BAS does require the driver to step on the brakes to benefit.
What is the problem with AEB?
Many of the complaints detail instances where the AEB system may have been triggered by railroad tracks, traffic lights, bridges, and other fixed objects. However, a not insignificant number of them also occurred with no obstacles in sight.
What are common disadvantages with automatic emergency braking?
Below are some of the disadvantages of the automatic emergency braking system.
- AEB is an expensive system. Hence, cars with automatic braking systems are expensive.
- Automatic braking can kick in falsely and jam the brakes.
- Some drivers can be over-reliant on AEB and may not pay attention to the road ahead.
How effective is automatic emergency braking?
AEB has been shown to reduce front impact crash rates by 27% [22]. The effectiveness at preventing pedestrian fatalities and injuries due to impact by the front of a car was 44% and 33%, respectively [9], the same as collisions with road obstacles.
What is the speed limit for AEB?
Some AEB systems operate only at city speeds, which are typically at 55 mph and below. Other AEB systems can work at highway speeds, which are typically above 55 mph.
Is it bad to use emergency brake all the time?
Drawbacks: Brake Wear: Regularly using the emergency brake can lead to excessive wear on the brake components, particularly if it's not designed for frequent use. Seizing: If the emergency brake is engaged too often, especially in wet or cold conditions, it can seize up, making it difficult to disengage.
Is AEB the same as ABS?
Both ABS and AEB are vital for vehicle safety, but they serve different purposes. ABS helps maintain control during emergency braking by preventing wheel lock-up, while AEB works to prevent collisions by automatically applying the brakes when a potential impact is detected.
Can you switch off AEB?
Turning Automatic Emergency Braking Off
You can turn the AEB feature off through the Settings menu of your infotainment system.
Does AEB reduce insurance?
Insurance companies calculate premiums based on risk, and vehicles equipped with advanced safety features, such as AEB, can reduce the likelihood and severity of accidents. However, often the presence of safety features like AEB don't lead to noticeably lower premiums.
What is the new AEB rule?
New Automatic Emergency Braking Requirement for Vehicles Built After 2029. The National Highway Traffic Safety Administration (NHTSA) has finalized a rule that requires all newly manufactured vehicles to have automatic emergency braking (AEB) capabilities as of September 1, 2029.
