As someone who has had the auto emergency braking (radar based) engage while the car was already on autopilot, I find this scary. Had it not been on, autopilot would have not slowed down fast enough and hit the vehicle in front of me. Also the fact that without radar they are limiting vehicles to 75mph means it's useless in Texas and many other states.
