I wasn't going to post this, but what the heck...
With the big charger diesels, you don't have a throttle pedal, you have a time-delay light-switch instead. You put in a request for some more HP, your request is processed and assessed:
"Hey Joe! The driver asked us for some more power."
"Yeah, I heard him, but I'm right in the middle of Days Of Our Lives, can it wait until the commercial break?"
"Sure, that should be no problem."
...
"OK, it's a commercial break. What did you want Stan?"
"Uh, let me think. Something about a driver request. I think he wanted some more power?"
"Did he say how much?"
"I forgot. Well, if a little is good, more is better. Give it all to him immediately, and if he doesn't like it, he can just make another request."
WHOOOSH!!!
It's what makes racing turbo diesels fun and scary at the same time.
