The U.S. Department of Transportation’s National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety announced today a historic commitment by 20 automakers representing more than 99 percent of the U.S. auto market to make automatic emergency braking a standard feature on virtually all new cars no later than NHTSA’s 2022 reporting year, which begins Sept 1, 2022.
but I can't find any information on how good this technology is at reducing bicycle crashes. But this seems hopeful
Automatic emergency braking includes a range of systems designed to address the large number of crashes, especially rear-end crashes, in which drivers do not apply the brakes or fail to apply sufficient braking power to avoid or mitigate a crash.
Rear-end crashes into cyclists are rare, but particularly deadly so any advance in that area would make cycling safer. But it sounds like pedestrian detection is still over the horizon a bit
To encourage further development of AEB technology, NHTSA will accelerate its research on more advanced AEB applications, including systems that reduce the risk of collisions with pedestrians.
