Modern automobiles use lots of chips. Copper wires have become very expensive, so instead of bundles of wires going from the dashboard to headlights, taillights, brake lights, low tire pressure indicators, etc., cars instead have a single high-current power bus and a local area network that talks to small modules controlling groups of lights, etc. Each module has a cheap microcontroller that talks to the LAN and turns nearby lights on and off. A modern automobile has many dozens of these microcontrollers as well as the power transistors that drive the light bulbs.

None of these chips require high-density semiconductor processes. 14 nm and above are fine, and are preferred for their robustness. They are perfectly suited to China's mass production skill.
