Experimenting? It’s been around for a long time. My 1999 Jetta had it. It’s smoother and you can control the fuel adder on throttle opening from all angles.
Sure, it’s not instant, but stabbing the gas in a non dbw is not great either.
In electric cars there is no other way than dbw
Well I see what you mean. Steer by wire is part of drive by wire if you want to be specific. But before that was a thing “drive by wire” meant a throttle body controller by the ECU.m for many years. So if you go to a shop and say DBW what the other end hears is “stepper throttle”
It's be really cool if there were some giant high power potentiometer connected directly from the batter to the motors in an EV. Just smash the pedal, see a blast of plasma and you take off. Just like slot cars. I can't see a single downside to this :p
