I like the concept of fly by wire- fewer things to break, fewer WAYS to break, easy to diagnose. And when you floor the pedal, the computer KNOWS to do whatever it can to give you 100% power. I know I've driven cars that need the throttle feathered to go as fast as possible, to ride the power curve if you will. Now the engineers can figure out a table of values and the car will, theoretically, be as responsive and as efficient as possible.
The downside with these things is that when they break, they usually just stop working. On the other hand, look at something like spark control computers- way, way, way, way more reliable and efficient than hall effect distributors or points. There are tons of cars that go their entire lives never needing any ignition work done. NONE. No changing distributor caps every 15,000 miles or adjusting points every 6000.
Of course, that assumes the engineers know what they are doing. I drove a Magnum with this system, and found it almost seamless. Except for a 1-2 second delay when you really wanted to pound on it.
OTOH, I drove a Nissan with it and really, really thought it performed better than a traditional one would.
