Auto Industry Group Pushes Back Against the NHTSA's Updated AEB Rules

Earlier this year, the National Highway Traffic Highway Safety Administration updated its rules on automatic emergency braking, opting to require that almost all new cars and trucks carry the feature by 2029. Now, a group representing most major automakers is pushing back, saying that the requirements are “practically impossible with available technology.”


The NHTSA’s updated rule requires cars and trucks to stop at speeds up to 62 mph, significantly faster than most offer today. The Alliance for Automotive Innovation, which represents GM, Toyota, and most others, noted that the higher speeds would require much earlier braking times from AEB systems, which could result in surprised drivers and rear-end collisions.

The Alliance’s CEO, John Bozzella, said the change “won’t improve driver or pedestrian safety.”

He also noted that the new rule “points to the breakdown of a deliberative rulemaking process at the country’s top traffic safety watchdog.” The NHTSA believes the change could save at least 360 lives and prevent 24,000 injuries annually.


In addition to stopping cars at up to 62 mph, the NHTSA’s ruling requires that AEB systems apply the brakes automatically at up to 90 mph “when a collision with a lead vehicle is imminent, and up to 45 mph when a pedestrian is detected.”

Many new vehicles come with AEB technology, but in addition to surprising drivers with earlier braking times, such a significant change in how the systems operate could result in higher costs for buyers as automakers look to recoup development costs. That said, it’s hard to argue against saving lives and preventing injuries.

    As of now I would side with the opposition camp. The technology is not mature enough or cheap enough. And even when it is it will only be effective for a few years until peoples Tires are no longer able to deliver optimal stopping power and control. At this point people's diminishing buying power woukd be better spent on more aggressive Brake nd Tire maintenence (and selection) than than another pricey tech gizmo that will cost thousands of dollars down the road for module replacement and bogus "reprograming" fees as it is with VDC, BCM's, TCM's Electric Steering ect.


    The first regulatory effort whould be to set minimum performance standards for approved Tires qnd aftermarket Brakes. And if higher operating costs are to be imposed on drivers it should first be on stopping and traction related maintenence. When I survey the cars jn my workplace and residential parking areas, I get chills from the age and condition of the tires on which at least 20% of people drive.

    I expect the Industry's opposition will soften if they get assurances that they will have no responsibility for covering this system beyond the basic warranty period so there is no chwnce of it becoming a more expensive version of the AirBag debacle.


    On the other hand I would be more supportive if the Feds force them to cover such mandatory safery features for the life of the car (with some tax credits for.doing so). REAL sustainability is being abke to affordably drive the car at least 25 years.

  • EBFlex No. I buy as little Chinese products as possible.
  • John "...often in a state of complete disarray on the roads" What does that mean? Many examples in poor repair? Talk about awful writing.
  • Varezhka Saving sedans in US or globally? Right now around half of the global sedan sales is in China, just under a quarter in North America, and the remaining quarter distributed around the rest of the world. So for a sedan to stay around they must sell well in both China and North America (BMW, Mercedes, Toyota, Honda) or just extremely well in China (VW/Audi and Nissan). For everyone else, the writing is on the wall. There’s also a niche of subcompact sedans in SE Asia and India but I believe those are being replaced by SUVs too.
  • Kcflyer it's not a ford, it's not a mustang. just like the ford gt is not a ford but multimatic gt or mustang wouldn't roll off the tongue
  • Kcflyer it's simple , most are too stupid to find china on a map , much less understand the evil of communism. which is, i guess, better then openly pushing to embrace communism/socialism......cough...dnc....cough
