Newer AEB systems surpass older ones but still struggle at high speeds

Newer automatic emergency braking systems prevent about twice the number of crashes that older models do but still fail to stop crashes at high speeds, a challenge for automakers preparing to meet a strict new federal standard for the technology.Model-year 2024 vehicles with automatic emergency braking avoided 100 percentof forward collisions at 35 mph, a much better performance than 2017 and 2018vehicles, which avoided collisions 51percent of the time at that speed, according to resea
