“...put the computer in charge of your car. It can override your inputs and decide what to do on its own.”
No, it can’t “decide to do what it wants” Quit reading those Stephen King Novels.
While you’re at it, put down the bong.
Actually that’s EXACTLY what those systems do. EFI doesn’t care if you jam the gas peddle down, it will increase the gas flow at the programmed rate. ABS flutters the brakes for you. Traction control changes power to the wheels. All of these systems OVERRIDE you. No Stephen King. No bong. Actually understanding how your car computer works.
