I've been paying particularly close attention to shortages along these lines. The chips and special parts going into our logistics system are at the root of making everything it transports possible. We don't even have the fancy AI trucks yet and yet the US runs on a network of semis and fleet trucks that are rapidly running out of replacement parts. The breakdowns in repair/production capacity are so scattershot that there's no telling what the transport delay will impact next. Those chips compete for production space with every other kind of vehicular computer system, let alone other kinds of chips a micorprocessor plant could retool to make.

Some of the stuff i work on have automatic fire extinguishers and about a dozen sensors to make sure the machines hydraulic brakes and gearbox dont fuck up. On modern cars, theres stuff to gauge the fuel levels, the brakes, temperature, timing, etc.
