I think some of the other new technology such has low speed collision control,  lane guidance and other new systems, alone. Electronic stability control is far more important, and saves far more lives.

But this would still be a good tool, but suspect very costly to implement and keep maintained. I can imagine it getting stuck and freezing on a frame, and giving the person the incorrect impression that the road is clear when not. Who would be liable if that occurred.

This issue also only affects those who overtake large trucks on single lane roads. Many people never take that risk, and in NZ we do usually have areas to the sides of road where trucks will pull over. Most truck drivers in NZ are also very considerate. You always get the odd one who isn't, but if they are holding up traffic intentionally, then police could pull them over and ticket them, as slow drivers are supposed to pull over and let drivers through.
