The false positive rate of this system could be very noisy. At what point should you brake, even if the AI says not to? When you might collide with a lidar point? You want to collide with lidar points all the time (the ground beneath the vehicle, for example, or any reflective noise). The AI is there to tell you what lidar points are actual obstacles that you can't collide with, otherwise it's not really meaningful.
