Earlier quoted context omitted.
I've idly thought that if I was the F1 Czar I'd ban all transistors in the cars, except for in safety equipment. Not even a radio. Have the operation of the car be up to driver skill, not computer programmer virtuosity. (And I'm a programmer!) Of course, it is possible to make mechanical computers, but they are very costly to develop, heavy, take up lots of space, hard to modify, etc. Besides, it's a lost art.
Transistors have been in racing cars since 1967 when the Cosworth DFV engine, with a "transistorized ignition" system, was put to the back of the Lotus 49, driven by Jim Clark and Graham Hill. Going all mechanical would be going back to an era long gone. It would be difficult to attract funding for a formula racing series (not a spec series) based on obsolete technology. That said, the early 1960s era of 1.5 liter V8…
