They need lidar/radar, then they have a chance to detect objects. Especially stopped traffic is a problem for vision only algorithms. It's easy to see moving objects, it's harder to see stopped objects. We humans are quite good at this, but machines have a long way to go here. Even with stereo view, everything that's a few hundred meters away doesn't have much difference between the left and right picture. Add to that that a few hundred meters away it's just a few pixels. So if it isn't moving it's like detecting a small object in a photo. Lidar/radar are the only sensors which can reliably detect stopped cars at a distance if you ask me.
