- Pedestrian detection systems do little to protect the people they detect, new data from AAA show.
- In tests on four new vehicles, researchers found that a crash is avoided less than half the time.
- For children, the results are even more expensive, with 89% of crashes happening despite the features.

High-tech safety features are almost ubiquitous in new cars, but new research shows that when it is most needed, technology may not do much to save lives.
tests by the American Automobile Association (AAA), automatic braking prevented only one collision with an adult less than half the time. For children, a collision was only avoided 1
For its tests, AAA used four different cars from 2019: Chevrolet Malibu, Honda Accord, Tesla Model 3 and Toyota Camry. All the cars had the manufacturer's specific automatic braking technology.
The sedans were then driven on closed streets on a California freeway, where scientists drove the cars on pedestrian-sized vehicles that traveled across the road like a normal person walking. The brake pedal was not pushed until after the car contacted the fake pedestrian, to monitor warning light as well as speed reduction due to automatic braking that started.
As you might expect, the systems performed even worse at night when there was less light. To be sure, however, the researchers note that most vehicle manufacturers warn that the systems may not work as well during these times.
There is some good news, fortunately.
When tested on adult-sized dummies, "said each test vehicle provided visual warning of an impending collision during each test run conducted at 20 km / h," and successfully avoided the collision 40% of the time, while reducing the stroke rate at about 6 miles per hour.
But when he came around a corner, "None of the test vehicles slowed down the speed during any of the five test runs."
"Never rely on pedestrian detection systems to avoid collision," AAA drivers recalled in its report. "These systems act as a backup rather than a primary means of avoiding a collision."
