2017 Throttle sticking for half second?

I guess I'll post this in general because I'm not convinced it is a "problem"...

Today I asked my 3 teen kids how they liked the Volt compared to the Challenger SRT that I traded and my boy says, "drift into the driveway and I'll give it respect". :) So I figured just after I turned into my driveway I'd stab the throttle to at least give them a little scratch. I stabbed the throttle to the floor and released it immediately and it did exactly what I wanted: tires screeched and it lunged forward BUT: it continued to accelerate for about a half second after my foot was completely off the accelerator which also resulted in a longer screech than I was expecting.

Is this a known "phenomenon" in the Volt? I was thinking maybe the motor controller takes a half second to disengage or that maybe it doesn't cut power instantly to prevent shock on the drivetrain? The end result is basically a non-issue I guess: I was just used to ICE being more instant on the release. It was strange feeling the accelerator pedal in the full up position but the car still accelerating hard for about a half second. Also seems strange that the power came ON immediately as soon as I stabbed it but took a half second to "roll OFF".

I remember when my mom put our '68 Impala 4 barrel through the garage door. I guess it didn't release quickly enough either ;)

Today almost all throttles are computer rather than cable controlled. What you describe doesn't surprise me at all. And it certainly doesn't concern me since no one actually has any need to drive like that.
He's not. He's 14. Have to teach them how to do a proper burnout early. :p
My kids are even younger, and I have to be so careful now that they pay more attention. My son now loves it when I'm in a hurry and zip around a corner. And my daughter has already admonished me for driving with alacrity. I want them to understand very clearly that these things are NOT ok.
