Not every radar out there is a Doppler radar. But you are right on the point of there being no silver bullet sensing technology. All of them have their own very glaring weaknesses. Radars are superior for simple collision avoidance for them being able to directly sense the velocity, but they are obviously useless for lane keeping. Lidars are super unreliable from both internal factors, and the environment. Basically, a splat of dirt, and a collision. Cameras are subject to all uncertainties of a CV system, and smog, smoke, and weather as well.
