Miles and disengagement data is useless and often hype without knowing the scenarios involved. Beyond that an increasing disengagement rate might be correlated to an increasing rate of exposure to new, especially more complex scenarios. We will not get that data until the wild west that can’t police itself comes full circle. Increasing and needless deaths caused by the untenable process of public shadow and safety driving, especially of a child or family, will drive the press who will drive lawmakers finally to create actual and mandatory detail test criteria. Not unlike what led us to the FAA.
