But it's not really that straight forward. You push the pedal, the computer runs an algorithm, and then throttle body moves. The algorithm is the part that you can't troubleshoot, mitigate, or fix.
I recently started driving a drive-by-wire vehicle. A while ago I had an issue where the engine dropped to a near-idle (on the freeway) and the pedal was effectively non-operative. The diagnostics said the computer wasn't getting the expected results from moving the throttle body, so it went into some kind of safe mode.
Now, there are plenty of ways that drive-by-cable could fail, but in this case I was slightly resentful because I could have mitigated the computer's loss of senses with my own.
