I guess I’m not seeing it as being all that different from emergency collision avoidance systems in cars with drivers in terms of drivers behind them. I hate to be dense about this, but I’m just not seeing why any of those maneuvers would make a difference to the driver behind the car driving autonomously if it was being driven by a human or not. Don’t you have to take the same actions regardless? I’m not suggesting Mercedes not do it. I’m sure people much smarter than me have figured out why this is important.

Maybe all cars with collision avoidance need to have these lights too?
