Emergency brake should not be compared with fully autonomous drive. Emergency brake is there to reduce the risk in case of driver error, given that the driver has already made an error. You should not need to know whether it's installed or not because you should not be making errors in the first place. Let's say for sake of simplicity that the system can reduce the risk with 50%. Under normal driving conditions when the risk of hitting somebody is say 0.0001%, you instead get 0.00005%, that can't be bad. If you provoke the system by actively aiming at a human you by definition have 100% risk of collision without the system, with it you have 50% of 100%=50%, I wouldn't want to be that pedestrian, even if the system could reduce down to 1%. Autonomous drive on the other hand, you give the car control, as opposed to the car taking it from you (because you have been a bad driver). If you give the car control then you should know the systems limitations and which responsibilities you are giving away. What is control anyway? Is cruise control a half-assed version of autonomous drive or not?
