the lag between human foot on a cable to the throttle body vs the electronics
figuring out what you are attempting to do allows too many emissions. having the computer intervene ahead of time ensures the ECU can keep within parameters and never go outside the envelope.

Never say never.

The TBW is more related to MPG, not emissions.
The ECU trying to figure out what you are tring to do is a never ending excersize in futility at best.

If the general public loses faith in the TBW system they, will design TB cable in future designs. It is a buyers market after all.

TBW seemed like a good idea a first but it is not standing up to the test of time.
The auto industry in in the mist or a high tech orgy and perhaps they need to rethink the TBW concept

IMO, throttles should be under the direct control of the driver just like brakes are.

Would you buy a car with a brake by wire sys where your brake pedal is only conected to an electric sensor?
I certainly would not.

I will say never on this. you stomp the gas on DBW, the computer decides
how fast to open it up. this is the only way cars can meet gov regs. gov regs are the issue. I would rather have direct like in my 4runner, but reality is, that is all going away.

drive by wire system are proven to be as reliable if not more reliable than old-school. but they need to be engineered and built properly like anything else, or they can and will fail. brakes will always have a fail-safe mechanism
which is some type of direct braking, in case all other systems fail.
