Most digital techniques that tackle some driving duties for people don’t adequately make sure that drivers are paying consideration, they usually don’t difficulty sturdy sufficient warnings or take different actions to make drivers behave, in keeping with an insurance coverage trade research revealed Tuesday.
Solely one among 14 partially automated techniques examined by the Insurance coverage Institute for Freeway Security carried out nicely sufficient to get an general “acceptable” score. Two others have been rated “marginal,” whereas the remainder have been rated “poor.” No system acquired the highest score of “good.”
“Most of them don’t include adequate measures to prevent misuse and keep drivers from losing focus on what’s happening on the road,” stated IIHS President David Harkey.

It additionally says it’s making an attempt to fill a “regulatory void” left by inaction on the techniques from the U.S. Nationwide Freeway Visitors Security Administration. Harkey stated the company must do extra to set requirements for the techniques, which aren’t capable of drive automobiles themselves.
The company stated Tuesday that it welcomes the IIHS analysis and can overview the report.
IIHS security rankings are carefully adopted by automakers, which regularly make modifications to adjust to them.
The 14 techniques, which embrace a number of variations from single automakers, are among the many most refined now in the marketplace, Harkey stated.
Solely one of many techniques, Teammate within the Lexus LS, earned the sufficient score. Basic Motors’ Tremendous Cruise within the GMC Sierra and Nissan’s Professional-Pilot Help with Navi-Hyperlink within the Ariya electrical car have been rated marginal.
Different techniques from Nissan, Tesla, BMW, Ford, Genesis, Mercedes-Benz and Volvo have been rated poor.
Harkey stated the driving techniques initially have been mixtures of security options reminiscent of automated emergency braking, lane departure warnings, lane centering and blind-spot detection. However now they provide drivers the possibility to not concentrate for some time frame, elevating security dangers, he stated in an interview.
“That’s why the focus is on how do we make sure that the driver remains focused on the driving task,” Harkey stated.
Some automakers, he stated, market the techniques in a manner that drivers might assume they’re totally autonomous. “The one thing we do not want is for drivers to misinterpret what these things can or cannot do,” he stated.
The techniques, IIHS stated, ought to be capable of see if a driver’s head or eyes should not directed on the highway, and whether or not their arms are on the wheel or able to seize it if mandatory.
The institute additionally stated if a system doesn’t see a driver’s eyes on the highway or arms aren’t able to steer, there ought to be audible and visible alerts inside 10 seconds. Earlier than 20 seconds, the system ought to add a 3rd alert or begin an emergency process to decelerate the car, the institute stated.
Automakers also needs to make sure that security techniques reminiscent of seat belts and automated emergency braking are activated earlier than the driving techniques can be utilized, it stated.
Not one of the 14 techniques met all the driving force monitoring necessities within the take a look at, however Ford’s got here shut, the group stated.
Lexus’ Teammate system and GM’s Tremendous Cruise met the warning necessities, whereas techniques from Nissan and Tesla have been shut.
Harkey stated automakers already are responding to the checks and getting ready modifications, a lot of which will be achieved with software program updates.
Toyota, which makes Lexus automobiles, stated it considers IIHS rankings in establishing security requirements, whereas GM stated the IIHS rankings are essential. Nissan stated it’s going to work with the institute.
Mercedes stated the corporate stated it takes the findings critically, and it depends on the system collaborating with the driving force, whereas Hyundai luxurious model Genesis stated it’s rapidly bettering its system, together with the addition of an in-cabin digicam. Volvo stated it helps IIHS efforts to scale back misuse of driver help techniques
BMW stated it respects IIHS’s efforts, however it differs philosophically about how techniques ought to monitor drivers. One BMW system evaluated by IIHS isn’t supposed for drivers to take their arms off the wheel and solely considers enter from steering wheel sensors. BMW checks haven’t discovered a transparent benefit in turning on the driving force monitoring digicam, the corporate stated. One other extra refined system supposed for drivers to take arms off the steering wheel makes use of a digicam to look at drivers, the corporate stated.
