Anything that reduces lag is a good thing. Making the pedal more responsive would be a good start... getting the throttle to respond to the pedal faster is what I want.
I am tired of my car taking the time to consider whether or not it "agrees" with the input I am giving it. Fly-by-wire cars suck for that reason. You would think that you could move electrons faster than a lever can move a steel cable, but no. Who ever decided to remove the direct link from your foot to the throttle was an hineyhole. Plenty of cars ran plenty well, and ARE STILL running plenty well, with that simple, even possibly archaic, set-up. Cam phase sensors and catalytic converter temperature readings honestly have nothing to do with how much gas I want... and I cannot stress this enough, I WANT (it is all about me)... so there are not any other inputs necessary and thusly, there should be ZERO computing time. Give me a one-for-one input, and give it to me NOW. That is how I want my throttle. That is how I want my steering.
Cadillac makes an excellent machine, but it is still just a machine, and therefor should do as it is told.
First of all, it's drive-by-wire not fly-by-wire. Perhaps what you intend to do is fly, we're sorry but these cars are incapable of that, perhaps you're confused about what this car can and can't do
And I'm sorry to say, but you make it sound like all automotive engineers know nothing about what they're doing and you know it all. Trust me there are reasons unfortunately beyond your comprehension that necessitate drive by wire / electronic throttle by wire.
The automobile of today is not that of yesterday, these cars are not that simple to engineer with all the electronic systems in them and the driver in full control over the throttle position doesn't make the implementation of more modern systems more simple.
Does electronic throttle control come with some disadvantages? Yes and is there a system that doesn't have pros and cons? And all drive-by-wire systems behave or are calibrated in the same way some are better than others and certain models of Cadillac might behave better than others. And the way these vehicles were engineered and calibrated also depends heavily on the demographic that this car was marketed to, that is a necessary business decision. But we don't hear many people especiially here on the forum complaning about the throttle in the CTS, I drive my car with a very heavy foot and I for one like the way it's calibrated and my dirving is in tune with it and it doesn't take joy away from my driving and I know many that feel the same.
Drive-by-cable is becoming more expensive and difficult to engineer as more electronic systems are introduced into these vehicles.
These systems are introduced into the vehicles due to market demand for technologies such as emissions control, ABS, torque management, stability control, traction control and so on, it's not only the companies that are just pushing them unto people, these systems require more engineering from the companies side, it's what people want at the end (indirectly) that drives such changes.
Unless you want to see by show of hands or should I say electronic hands?? hehe who doesn't want these systems in their vehicle!
