Geofencing
It would not be that expensive or difficult for Tesla and other autonomous-capable vehicle makers to geofence their products -- provide an over-the-air and regularly updated "map" of problem areas like construction zones on interstates and motorways that would alert the driver ("Wake up you dozy idiot!!!" at 110dB, I respectfully suggest) as they approached the area and then disable Autopilot or the equivalent function once the driver has taken control. If they failed to do so or refused to do so then the car would divert to the hard shoulder and stop since it's too dangerous to proceed in that case.
