>It is crazy to get into my partner's mid-2010s sedan and laugh at how bad the lights are at nighttime compared to the perfectly aimed and calibrated Subaru lights

On the other hand, that mid 2010s sedan's headlight system will age gracefully - there are no aiming servos to fail or autodim relay output to stop working or such thing. It's just lights with a switch to turn them on or off.

Increased complexity also implies increased maintenance and often more troublesome failure modes when something does fail.

I would find it hard to believe that the failure mode of these headlights wouldn't be "points straight and doesn't auto-dim ever", which reduces it to the previous implementation's graceful aging modes, but you are right a new possibility is introduced.

I would absolutely believe the failure mode will be that one headlight will stop moving when it's commanded to, which best case means straight headlight, worst case means aimed where it shouldn't be 99% of the time

And whatever those failure modes are, they better be good, because in 20 years those vehicles will be on the road in some state without regular inspections, driven by someone without the money to pay for OEM electrical repairs.
