There are physical limits to how good a radar's resolution can be, set by the properties of the radio waves used. Those make it really difficult to detect small size differences -- relative to the radar's wavelength -- though, not quite impossible.
It's why everyone else uses lidar instead, or in addition. Really, it has the same limits, but the wavelength of visible light is small enough that they're only an issue for microscopes.

You physically see what the driver would physically see and react how the driver would react with the same information (just faster). See Subaru, Toyota, Honda, etc. I'm not sure why this article and this discussion seemingly act like the predominant technology used in automatic braking systems doesn't exist?
