Also, no way in hell a car has even the computing power of one PC.
I used to do embedded systems for the industry on the software side (dashboards, door locks, keyfobs, etc). It's true that basically anything you consider a component has it's own integrated CPU, it's also an extremely weak CPU.
PIC-16s and similiar were the CPUs mostly used. We're talking 1MB of RAM, sub 50 MHz chips. There might be 100 of these, but that's still less computing power than a single mid-range CPU will give you these days. Sure, there are some more powerful CPUs in certain components, but none of them will even approach a desktop CPU.
