Sure, but such systems won't work at all if they don't ignore such stationary objects as bridge abutments. And they lack the angular resolution to determine whether stuff is directly ahead, or off to one side. Plus the fact that roads curve.

Or, as in the Thatcham Research video, stuff that's hidden by a leading vehicle. I always make an effort to know what vehicles far ahead are doing. If necessary, I shift off lane occasionally to check for hidden stuff. And when I'm behind large vehicles, I don't follow so closely that I can't see what's ahead.

But if you're going to do all that, why use Autopilot?
