Industry News: New Study Says Drivers Aren't Aware of the Limitations Of Assistance Systems

Many new cars are fitted with various driver assist systems; backup cameras, blind spot monitoring, adaptive cruise control, forward collision warning, and lane-keep assist to name a few. But this has introduced the problem of drivers becoming too reliant on these systems, causing them not realize the limitations and taking their own "preventative measures".

The AAA Foundation for Traffic Safety published a report this month looking into drivers' experiences with the assistance technologies and seeing how they relate to their understanding of it. The group commissioned researchers from the University of Iowa to survey over 1,200 owners of 2016 and 2017 model year vehicles equipped with ADAS technologies.

The study revealed that the majority of drivers have a favorable impression of ADAS tech, with at least "two in three owners of vehicles with each respective technology reported that they trusted it." Seven out ten respondents said they would want the respective ADAS tech on their current vehicle to be standard on their next one.

But, the study revealed that many drivers overestimate the capability of ADAS systems. Here are some of the key findings,

  • Over 80 percent of drivers surveyed don't fully understand the limitations or believed that blind-spot monitoring systems could detect a large number of  fast-approaching vehicles, bicycles and pedestrians.
  • 25 percent of drivers surveyed said they don't look for oncoming vehicles when they change lanes because their vehicle has blind-spot monitoring.
  • Nearly 40 percent of drivers don't understand the limitations of forward collision warning and automatic emergency braking systems. A number believed that the former would bring the vehicle to a stop, when in actuality only warns a driver of a possible collision.
  • One in six drivers didn't know if their vehicle came equipped with an emergency braking system.
  • About 29 percent of drivers admitted "feeling comfortable engaging in other tasks while driving" when using the adaptive cruise control system.

“When properly utilized, ADAS technologies have the potential to prevent 40 percent of all vehicle crashes and nearly 30 percent of traffic deaths. However, driver understanding and proper use is crucial in reaping the full safety benefits of these systems,” said Dr. David Yang, executive director of the AAA Foundation for Traffic Safety in a statement.

“Findings from this new research show that there is still a lot of work to be done in educating drivers about proper use of ADAS technologies and their limitations.”

AAA says automakers, dealers, and rental agencies need to provide better education to drivers about ADAS tech and their limitations.

Drivers Rely Too Heavily on New Vehicle Safety Technologies In Spite of Limitations

  • Misunderstanding and misuse of driver assistance technology could lead to a crash

WASHINGTON, D.C. (Sept. 26, 2018) – More and more, drivers are recognizing the value in having vehicles with advanced driver assistance systems (ADAS) like blind spot monitoring systems, forward collision warning and lane keeping assist. However, while many of these technologies are rapidly being offered as standard, many drivers are unaware of the safety limitations of ADAS in their vehicles, according to new research from the AAA Foundation for Traffic Safety. For example, researchers found that nearly 80 percent of drivers with blind spot monitoring systems were unaware of limitations or incorrectly believed the system could accurately detect vehicles passing at very high speeds or bicycles and pedestrians. In reality, the technology can only detect when a vehicle is traveling in a driver’s blind spot and many systems do not reliably detect pedestrians or cyclists. Lack of understanding or confusion about the proper function of ADAS technologies can lead to misuse and overreliance on the systems, which could result in a deadly crash.

“When properly utilized, ADAS technologies have the potential to prevent 40 percent of all vehicle crashes and nearly 30 percent of traffic deaths. However, driver understanding and proper use is crucial in reaping the full safety benefits of these systems,” said Dr. David Yang, executive director of the AAA Foundation for Traffic Safety. “Findings from this new research show that there is still a lot of work to be done in educating drivers about proper use of ADAS technologies and their limitations.”

In 2016, more than 37,400 people were killed in traffic crashes- a five percent increase from 2015. “With ADAS technologies offering proven safety benefits when properly used, it is important that automakers and others play a greater role in educating motorists about the technology available in the vehicles they purchase,” said Jake Nelson, AAA director of traffic safety advocacy and research. “AAA also urges drivers to take charge of learning their vehicle technology’s functions and limitations in order to improve safety on the road.”

The AAA Foundation for Traffic Safety commissioned researchers from the University of Iowa to survey drivers who recently purchased a 2016 or 2017 model-year vehicle with ADAS technologies. Researchers evaluated drivers’ opinions, awareness and understanding of these technologies and found that most did not know or understand the limitations of the systems:

  • Blind spot monitoring: 80 percent of drivers did not know the technology’s limitations or incorrectly believed that the systems could monitor the roadway behind the vehicle or reliably detect bicycles, pedestrians and vehicles passing at high speeds.
  • Forward collision warning and automatic emergency braking: nearly 40 percent of drivers did not know the system’s limitations, or confused the two technologies- incorrectly reporting that forward collision warning could apply the brakes in the case of an emergency when the technology is only designed to deliver a warning signal. Moreover, roughly one in six vehicle owners in the survey reported that they did not know whether or not their vehicle was equipped with automatic emergency braking.

False expectations for ADAS systems can easily lead to misuse of the technology or an increase in driver distraction. In the survey:

  • About 25 percent of drivers using blind spot monitoring or rear cross traffic alert systems report feeling comfortable relying solely on the systems and not performing visual checks or looking over their shoulder for oncoming traffic or pedestrians.
  • About 25 percent of vehicle owners using forward collision warning or lane departure warning systems report feeling comfortable engaging in other tasks while driving.

“New vehicle safety technology is designed to make driving safer, but it does not replace the important role each of us plays behind the wheel,” Yang continued. “The prospect of self-driving cars is exciting, but we aren’t there yet.  Automakers have an ethical and important responsibility to accurately market, and to carefully educate consumers about the technologies we purchase in the vehicles we drive off the lot.”

As part of its ongoing traffic safety mission, new AAA Foundation research also evaluated the potential these popular advanced driver assistance technologies have in helping to reduce or prevent crashes. The findings show that if installed on all vehicles, ADAS technologies can potentially prevent more than 2.7 million crashes, 1.1 million injuries and nearly 9,500 deaths each year:

ADAS Systems Crashes Injuries Deaths
Forward Collision Warning/ Automatic Emergency Braking 1,994,000 884,000 4,738
Lane Departure Warning / Lane Keeping Assist 519,000 187,000 4,654
Blind Spot Warning 318,000 89,000 274
Total Potentially Preventable by all systems  2,748,000 1,128,000 9,496

Despite the findings that show confusion about some ADAS technologies, at least 70 percent of vehicle owners report that they would recommend the technology to other drivers. The greatest proportion of drivers reported trusting blind spot monitoring systems (84 percent), followed by rear-cross traffic alert (82 percent), lane departure warning (77 percent), lane keeping assist (73 percent), forward collision warning (69 percent) and automatic emergency braking (66 percent).

These findings should prompt additional focus on the importance of educating new and used car buyers about how safety technologies work. “The training drivers need to properly use the safety technologies in their vehicles is not currently offered,” added Nelson. “If educating consumers about vehicle technology was as much a priority for the automakers and dealers as making the sale, we would all reap the benefits.”

Only about half of the drivers who report purchasing their vehicle from a car dealership recalled being offered a training on the ADAS technology. However, for those who were, nearly 90 percent took advantage of the opportunity and completed the training.

For now, drivers are their best safety advocate to ensure that they understand their technology’s features, functions and limitations before leaving the lot. In order to reduce misuse or overreliance on the systems, AAA encourages drivers to:

  • Read up: Read your owner’s manual to learn what systems are installed in your vehicle.
  • See it in action: Insist on an in-vehicle demonstration and test drive to better understand how the systems will engage on the roadway.
  • Ask questions: Ask plenty of questions about the alerts, functions, capabilities and limitations of the vehicle’s safety technologies before leaving the dealership. For example, ask if there are scenarios when a technology will not function properly on the road.

So true, Driving is a skill you have to pay attention too and not one to rely on computers. So many need to put their shit down and pay attention to the road.

After all, it is a Privilege earned not a right to drive.
