Keeping this in consideration, can a car run without a computer box?

Yes, it's true. Most cars prior to about 1980 had no computers in them at all. Carburetors and some forms of mechanical fuel injection operate without computer control - even though all modern cars use electronic fuel injection of some form, to my knowledge.

Similarly, what is the computer in a car called? Throughout the car are various computers called electronic control units, or ECUs—the traffic lights and intersections of our road-system analogy. Each ECU has several jobs: controlling the engine or transmission, rolling up windows, unlocking doors, and the like.
