Waymo mentions this in their safety report, which I think is interesting, and relevant: > Advanced driver-assist technologies were one of the first technologies our teams explored. In 2012 we developed and tested a Level 3 system that would drive autonomously on the freeway in a single lane but would still require a driver to take over at a moment’s notice. During our internal testing, however, we found that human drivers over-trusted the technology and were not monitoring the roadway carefully enough to be able to safely take control when needed. > As driver-assist features become more advanced, drivers are often asked to transition from passenger to driver in a matter of seconds, often in challenging or complex situations with little context of the scene ahead. The more tasks the vehicle is responsible for, the more complicated and vulnerable this moment of transition becomes.
