Uh, what?
I think you're thinking of Doppler radar systems. You can do static scene imaging with radar, no problems (I've written the code to do it, even!).
There's no way in hell a car is going to be using a Doppler radar. In all likelyhood, they're using a plain-old FMCW system, and it can absolutely detect stationary stuff.
