At the low end of automation, there is the long precedent of cruise control being legal. (I assume this applies to TACC also; maybe some lawyer can weigh in.)

At the low end of automation, there is the long precedent of cruise control being legal. (I assume this applies to TACC also; maybe some lawyer can weigh in.) Likely almost everyone agrees a excellent-human-driver general-AI grade of full automation should be legal; with a to-be-determined degree of manufacturer liability when a collision occurs. All of the dispute between those extremes boils down to this: Should there be a range of automation that is illegal to make and/or use? What should that range be? What current cars fall in the range? Should the illegality be based only on the technical performance, or also on the branding? When such illegal use happens, who all should be liable / punished?
