Improved driver assistance systems are becoming more and more common, but when other road users do something unexpected, they are still struggling to keep drivers safe, according to a new study AAA.
The association tested a collection of cars from brands such as Tesla, Hyundai and Subaru Semi-autonomous functions of the 2nd level which have been designed to help owners with the task of management. During a closed-course test, he sought to find out how these vehicles work when the vehicle in their lane is moving slowly, compared to how they behaved when the oncoming car drove into their lane.
The results of the first test were encouraging: vehicles in all 15 test runs slowed down and avoided collisions with slow-moving advanced vehicles. However, in what AAA calls the “limit case,” no system has been able to avoid a head-on collision with an oncoming vehicle drifting into their lane in any of the 15 test runs.
ADAS systems performed slightly better in tests involving bicycles, avoiding cyclists moving in the right direction along their lane. When bikes were driven perpendicular to the vehicle, as if the cyclist was trying to cross the road, a collision occurred in 33 percent of cases, and that’s not enough, says Greg Brennan. AAA director of automotive engineering.
“While it may be encouraging that these control systems have successfully spotted slow cars and cyclists on the same lane, it is alarming that you did not notice a cyclist or an oncoming vehicle, ”Brennan said. “A head-on crash is the deadliest species, and these systems need to be optimized for situations where they can help the most.”
The association believes that despite claims that these systems are designed to ease the burden of driving, tests have shown that drivers should stay fully focused on driving tasks to prevent any accidents. Previous AAA tests showed that ADAS systems are struggling in other areas as well, such as maintaining lanes on real roads.
Indeed, it seems that Brennan is not the only one who thinks the systems are inappropriate. In an AAA poll, 77 percent of consumers said they were more interested in carmakers improving existing security systems than in profit self-driving cars. Since the organization began studying automated driving functions, consumers have become less skeptical about the technology: 85 percent said they are unsure of the car.
