Most Drivers Say Safety Systems Helped Prevent Crashes, Survey Shows

For our survey, we asked CR members to tell us about their experiences with ADAS in their own cars. They provided data on about 72,000 vehicles, model years 2015-2019. They also provided about 87,000 comments on the individual ADAS features. Here are just a few examples of what younger drivers had to say:

“This [AEB] has saved me from a couple of highway accidents where someone cuts me off and then brakes suddenly,” a 34-year-old CR member from Minnesota told us about his 2018 Volkswagen GTI. “The car detected it, gave an audible warning, and braked firmly.”

The FCW system in a 2018 Subaru Forester saved a 28-year-old CR member in New Jersey from a potential accident when sunlight made it impossible to see the brake lights on a bright-red pickup in front of her. “I didn’t see his brake lights (they blended in), but the system beeped to notify me that he had stopped. This is a great system!” she commented in our survey.

And a 33-year-old CR member from Missouri said the AEB system on his 2017 Toyota RAV4 Hybrid has kept him out of two accidents. “One while I was glancing in a mirror and the driver had slammed on their brakes. Another when a deer jumped in front of me,” he told us. Over the past decade, there's been a huge increase in the availability of advanced driver-assist systems in cars sold in the U.S., starting with FCW and AEB, and expanding to BSW, lane departure warning (LDW), lane keeping assistance (LKA), and most recently, pedestrian detection systems. Because they’re proving effective, CR gives extra points to the Overall Score for tested models that have the following systems as standard equipment across all trim lines: FCW, highway-speed AEB, city-speed AEB with pedestrian detection, and BSW.

BSW is becoming an ever-more-critical safety feature, because many of today’s new cars are designed with thick roof pillars to help provide a strong crash structure. Those thick pillars make new vehicles considerably harder to see out, which can lead to accidents with vehicles in larger blind spots.

BSW systems help by indicating when there’s a vehicle on either side of your car, warning about what's potentially in your blind spot. The system gives a visual alert—usually on the side mirror or mirror frame, or near the base of the front pillar—to indicate that it might be unsafe to merge or change lanes. Some systems provide an additional, audible warning when the turn signal is activated if a car is in a lane next to you.

BSW was universally liked across the age groups in our survey, but like AEB, older drivers rated their satisfaction with the system higher, with drivers under 35 the least happy (at 71 percent very satisfied vs. a high of 83 percent for drivers 65 to 84). Drivers of all ages reported that BSW helped them avoid a crash.

“These advanced technologies can offset some of the risks of distracted driving, but they aren’t meant to be a replacement for being fully engaged in the driving experience,” says Fisher. “And being more attentive behind the wheel is something that every driver can—and should—apply every time they head out on the road, regardless of their age or experience level.”
