AAA believes testing, experience and education will aid consumer acceptance

ORLANDO, Fla. (Mar. 14, 2019) – A year after a number of high-profile automated vehicle incidents, American attitudes toward fully self-driving cars have not rebounded. AAA’s annual automated vehicle survey found that 71 percent of people are afraid to ride in fully self-driving vehicles – indicating that overall sentiment has not yet returned to what it was prior to these incidents occurring (63 percent). AAA believes the key to helping consumers feel more comfortable with fully self-driving vehicles will be bridging the gap between the perception of automated vehicle technology and the reality of how it actually works in today’s cars.

“Automated vehicle technology is evolving on a very public stage and, as a result, it is affecting how consumers feel about it,” said Greg Brannon, AAA’s director of Automotive Engineering and Industry Relations. “Having the opportunity to interact with partially or fully automated vehicle technology will help remove some of the mystery for consumers and open the door for greater acceptance.”

Experience seems to play a key role in impacting how drivers feel about automated vehicle technology. Many cars on the road today are equipped with advanced driver assistance systems (ADAS), which are considered the building blocks for fully self-driving vehicles. AAA’s recent survey revealed that regular interaction with ADAS components like lane keeping assistance, adaptive cruise control, automatic emergency braking and self-parking significantly improves consumer comfort level. On average, drivers who have one of these four ADAS technologies are about 68 percent more likely to trust these features than drivers who don’t have them.

Even more promising, AAA found that Americans are receptive to the idea of automated vehicle technology in more limited applications. About half (53 percent) are comfortable with low-speed, short distance forms of transportation like people movers found at airports or theme parks while 44 percent are comfortable with fully self-driving vehicles for delivery of food or packages. However, once the passengers become more personal – in particular, transporting their loved ones – one in five remain comfortable.

“Despite fears still running high, AAA’s study also shows that Americans are willing to take baby steps toward incorporating this type of technology into their lives,” continued Brannon. “Hands-on exposure in more controlled, low-risk environments coupled with stronger education will play a key role in easing fears about self-driving cars.”

Recently, AAA Northern California, Nevada & Utah, in partnership with the city of Las Vegas, Keolis North America and the Regional Transportation Commission of Southern Nevada (RTC), piloted the first and largest self-driving shuttle for the public to operate in live traffic, in an effort to give more people the opportunity to gain real-world experience with automated vehicle transportation. The self-driving shuttle was the first in the country to be fully integrated with smart city infrastructure and operate on open, public roads. Participants had the voluntary opportunity to take a survey post-ride regarding the impact of their personal experience with the shuttle on their perception of self-driving vehicles. Of those who responded, many reported their sentiment improved following the experience of riding the shuttle.

Currently, more than half of Americans (55 percent) think that by 2029, most cars will have the ability to drive themselves, however, this timeline may be overly optimistic given the number of vehicles already on the road today. Those who are skeptical that fully self-driving cars will arrive that soon, cite reasons such as lack of trust, not wanting to give up driving, the technology won’t be ready and that road conditions will not be good enough to support the technology.

While experts agree that a fully self-driving fleet is still decades away, it is likely that more highly automated vehicles will be on the roads in the coming years. The more drivers understand both the benefits and limitations of the technology that is currently available, AAA believes the more prepared and receptive they will be for the experience of riding in a fully automated vehicle when the time comes.

To help educate consumers on the effectiveness of emerging vehicle technologies, AAA is committed to conducting ongoing, unbiased testing of automated vehicle technologies as well as researching how related emerging technologies can help reduce or prevent crashes. Previous research includes ADAS technology naming, testing of driver support systems and the annual automated vehicle survey (2016, 2017, January 2018 and April 2018).

Methodology

A telephone omnibus survey was conducted January 10-13, 2019. A total of 1,008 interviews were completed among adults, 18 years of age or older.

A dual-frame approach was used that combined landline and cell phone interviews to ensure that adults who only or primarily communicate via cell phones are included and properly represented. Survey responses are weighted by six variables (age, gender, geographic region, race/ethnicity, education, and landline vs. cell phone only) to ensure reliable and accurate representation of the total continental US population, 18 years of age and older.

The margin of error for the study is 4% at the 95% confidence level. Smaller subgroups will have larger error margins.

ORLANDO, Fla. (Nov. 14, 2018) – A new survey from AAA finds that 40 percent of Americans expect partially automated driving systems, with names like Autopilot, ProPILOT or Pilot Assist, to have the ability to drive the car by itself, indicating a gap in consumer understanding of these technologies and reality. AAA also tested these systems and found that they are in fact not designed to take over the task of driving and can be significantly challenged by every day, real-world conditions such as poor lane markings, unusual traffic patterns and stationary vehicles. As this type of technology becomes more commonplace on the road, AAA cautions consumers not to take vehicle system names at face value and, although meant to assist in the driving task, should never be used as a replacement for driver engagement.

“With today’s exciting advances in vehicle technology, there is a greater need for naming that clearly signals to a driver what the system does,” said Greg Brannon, AAA’s director of Automotive Engineering and Industry Relations. “Vague or confusing terminology may lead someone to overestimate a system’s capability, unintentionally placing the driver and others on the road at risk.”

In partnership with the Automobile Club of Southern California’s Automotive Research Center, AAA tested four vehicles equipped with systems that combine technologies such as adaptive cruise control and lane keeping assist to help maintain lane position, forward speed and following distance in relation to a lead vehicle. Closed-course and on-road testing evaluated performance in typical driving situations where the technology generally behaved as expected. However, there were a number of instances in both environments that caused these systems to act in an unpredictable manner, requiring driver intervention to avoid a potential collision.

While driving on public roadways, AAA found test vehicles struggled when encountering scenarios that included moderate traffic, curved roadways and streets with busy intersections. Researchers noted many instances where the test vehicle experienced issues like lane departures, hugging lane markers, “ping-ponging” within the lane, inadequate braking, unexpected speed changes and inappropriate following distances. AAA’s study also revealed that nearly 90 percent of events requiring driver intervention were due to the test vehicle’s inability to maintain lane position. The irregular and complex nature of the real-world driving environment revealed the vulnerabilities of this technology. AAA’s testing found the systems generally performed best on open freeways and freeways with stop and go traffic.

During closed-course testing, common driving situations were simulated such as staying within the lane at 45 mph, following a distracted or impaired driver, encountering a commercial vehicle, for example, a tow truck, or contending with a vehicle that suddenly changed lanes to reveal a stationary vehicle. All test vehicles were able to successfully maintain lane position as well as recognize and react to the presence of the tow truck with little to no difficulty. However, in the scenario where a lead vehicle changed lanes to reveal a stationary one, three out of the four test vehicles required driver intervention to avoid an imminent crash. In general, this scenario is a stated limitation of these systems, however, it is a relatively common occurrence on roadways and could take those drivers by surprise who have become too reliant on the technology.

“Both real-world and closed-course testing exposed separate yet equally serious limitations with these systems,” said Brannon. “It reinforces that there is still much work to be done to educate consumers on the nuances between system names and functionality and that it is much too early to refer to these vehicle technologies as automated.”

In order to reduce the misuse of partially automated vehicle systems, AAA encourages drivers to educate themselves by requesting a demonstration at the dealership as well as thoroughly reading the vehicle owner’s manual. As this technology becomes more prevalent, standardized naming across vehicles that clearly reflects how technology functions will be necessary. Greater consistency across the industry will help consumers understand the type of technology their vehicle has along with how, when and where to use these systems.

To assess the capabilities of partially automated vehicle systems, AAA conducted primary research in partnership with the Automotive Club of Southern California’s Automotive Research Center in Los Angeles, California. Track testing was conducted on closed surface streets on the grounds of Auto Club Speedway in Fontana, California and was rented by AAA for independent testing. Public highway evaluation was conducted on surface streets, highways and limited-access freeways throughout the greater Los Angeles area.

Four test vehicles were selected (2018 Mercedes-Benz S-Class, 2018 Nissan Rogue, 2017 Tesla Model S and 2019 Volvo XC40) using specific criteria and each test vehicle was outfitted using industry‐standard instrumentation, sensors and cameras to capture vehicle dynamics, position data and braking intervention. Complete methodology can be found in the full research report at newsroom.aaa.com.

The consumer survey was conducted October 4–7, 2018, using two probability samples: randomly selected landline telephone and mobile (cell) phone numbers. The combined sample consisted of 1,003 adults (18 years old and older) living in the continental U.S. The margin of error for the study is 4% at the 95% confidence level. Smaller subgroups will have larger error margins.
