There is a moral hazard with ADAS + human drivers:

> Once drivers move from the novelty phase to the post-novelty operational phase, behavioral adaptation may begin to occur and overreliance and over-trust in the automation features potentially develop, including a greater willingness to look away from the forward road (as shown in the VCC data set). [1]

I'm not sure if this is more dangerous than strictly human-operated vehicles, but I would wager that it is more dangerous than strictly autonomous vehicles.
