You always see a giant stationary object in front of you - the road itself. The way you can tell the difference between the rock and the road itself is through additional resolution, reflectance and colouring information that is available at visible light wavelengths but not to radar.
So it's not a problem that can be solved through radar alone, you do need to combine that data with other sensors.

False alarms are an annoyance but a small price to pay. Even my tiny garmin dashcam has a basic collision alarm feature when it sees an object growing in size.
