I don't see what lidar has to do with any of this. No car on sale today has lidar, and yet plenty of them perform speed-adaptive cruise control with varying degrees of steering assistance, from none to hands-off-wheel. They use radar. Tesla cars also use radar. The question is whether the various software algorithms that interpret sensor information are being too quick to dismiss the apparent presence of stationary objects on the road. My understanding is that most—if not all—adaptive cruise control and autonomous emergency braking systems are unreliable when it comes to reacting to stationary objects at highway speed.
