I didn't read the article but these days a turn signa,for instance, doesn't just connect to a flasher and a bulb. It connects to the network in the car and requests that the computer initiate the turn signal. This means the turn signal switch itself has to have a chip in it to communicate with the network that I believe they are calling a sort of computer. Virtually every component in the car operates like this. It really isn't the same thing as 100 computers..
