The Transportation Department projects the new rule could save 360 lives a year and prevent 24,000 injuries.
The Biden administration plans to require that all new cars and trucks come with pedestrian-collision avoidance systems that include automatic emergency braking technology by the end of the decade.
In an interview, Transportation Secretary Pete Buttigieg said the requirement is designed to reduce pedestrian deaths, which have been on the rise in the post-Covid 19 era.

The new standards will require all cars to avoid contact at up to 62 mph and mandate that they must be able to detect pedestrians in the dark. They will also require braking at up to 45 mph when a pedestrian is detected.

If it’s radar based it should be very reliable. The big issue is camera based stuff. Cameras can’t measure much, only colour and brightness. From this everything is inferred not measured. Inferring things isn’t inherently bad, but the errors need to be accurately known and considered. They probably are, it’s just they are not weighted correctly relative to cost.
Two cameras can measure distance as well. It’s how our eyes work and how things like 3D scanners work.
Stereoscopic camera systems exist and they can work very well (like on my ten year old car).
They still don’t measure distance, they only infer it by comparing two images. This still has the same issue. It’s just a more reliable way to infer distance than a single camera. It also requires less processing, hence it was popular for earlier computer vision applications.
