You'd think some people would want to opt out of the fake/amplified engine noise, so they can drive in peace, listen to their stereo without interference, etc. but i guess making the amplified/fake engine noise an option would defeat the purpose.
Don't worry, it won't be disconnect a wire, but change a bit in the compute unit and make sure the compute unit code and data are cryptographically signed and that its signature is verified by all other compute units so that you may not even start the engine should you decide to alter it.
