The middle road is missed here. There are two problems, long duration supplies of a chip on the same process, and the cost of making chips. If the semiconductor companies can figure out an ASIC/FPGA type strategy that would allow any of the current chips in a car be produced "dynamically", then the semiconductor company could achieve their economies by just fabbing one design, and car companies could achieve longevity by getting commitments for production of that one design. Xilinx recently made some steps in a new direction by producing what they called an "RF" SoC. Where RF stands for radio frequency. Basically it had all of the analog to digitial and digital to analog bits on the chip in addition to some FPGA fabric and some ARM AARCH64 cores. Its expensive and small quantity but I think it will turn out to be important in the long run as the vanguard of chips that are not 'type specific' at the time of manufacture. Imagine a company that has the same basic FPGA architecture, packaged in a variety of automotive spec packages, with one-time programmability. That would reduce the number of SKUs considerably (basically by package type).
