Yep. More to the point, the list of mandatory technologies now include ABS, stability control, and backup cameras. The first two are
active features that to some extend remove control from the driver. They are required because the data on their net efficacy is overwhelming.

I don't have the numbers, but I bet that net-net they
save money. They start out expensive, but when required, the volumes are so high that they end up costing almost nothing on the margin. Moreover, they greatly reduce insurance costs.

In the future, will all cruise control system need to be adaptive? Will all cars require pre-collision assist and lane keeping assist?

Surely the answer to all these questions is certainly "yes". And it won't stop there. We will soon be seeing federally-mandated vehicle-to-vehicle communications. If your car's systems can see everything that the car ahead of you can see, that is a game changer. This will also permit "convoy" driving, in which clusters of cars drive together in clusters--just a few feet apart. Driving in each other's slip-streams will save vast amounts of energy, and in itself greatly increase the range of EVs. This can be done very safely if and only if the vehicles communicate.

Will manufacturers be legally liable for the functioning of these systems? Will highway maintenance crews be liable for a failure of someone's lane keeping assist because they didn't keep on top of lane painting?

These are good questions, and it will all have to sort itself out. But, it isn't completely new territory. Are these liability issues really all that different from those of, say, a malfunctioning traffic light or a missing crash barrier? Many of the most important safety technologies reside not in the vehicle but on the highway. They have to be maintained just as carefully as the vehicles are.
