Precedent set by older, and very similar, technology seems pretty relevant if we’re talking about liability
I think we are talking on similar, but not the same, situation.
In your case, absolutely you cannot rely on the car 100% to brake and its your liability.
But when cars are mandated to have some very specific technology, which will require the driver to get used to etc.
What if that technology fails? IE like Tesla autopilot at the moment. The more vehicles are regulated to have “self control” on braking etc even up to self driving, at what point does liability shift from the driver to the manufacturer?
At no point would or should the liability shift. Even in the case of autopilot. The driver still remains in complete control of the vehicle and it is their responsibility to not crash it. These automatic braking systems kick in at the last possible second. Things are already pretty bad if they are doing their job
