Why Carmakers Can’t Transition to Newer Chips

I seem to recall, several years ago (when stopping the engine at traffic lights and restarting as soon as the driver released the brake), at least one company was exploring moving to 24V. However, the effort failed precisely because the lifetime of 24V switches was significantly shorter.

Naturally, I can't find any links to the info...

Trucks and agriculture equipment already use 24V systems, so the point is moot. Vehicle usage during the lifetime of a truck greatly exceeeds the lifetime of a personal passenger vehicle and agriculture equipment is also exposed to dust and grime, yet both continue to operate normally. So I guess it's more of a cost problem than a component issue.

FWIW Almost no switches in a modern car (turn signals, wipers, door switches) carry a significant amount of current as they are controlled via confuzers.

Just built a car without a single relay. I used PMUs (basically boxes of mosfets and current sensors AFAIK).
