Commentary in racing games is always terrible and probably always will be. As wide-open and varied as GT is it would probably be completely ridiculous. It's generally poor in any game, but tends to work a little better for more "standard" sports. Still usually too repetitive, late and often random. It's really only best for the silly and or completely inappropriate things they say, and/or goofy memes.
"Just a bit of a knock on the wall there, I think." "You're right there, Murray."
"Jarno is running much faster than you. Maybe you should have a look at his setup." [Ok, that one wasn't technically commentary.]
"Boom! He's on his back."
"Quarterback can't hold the ball that long!"
"Where'd that truck come from?"
"No one catches the lob pass."
"It's a beautiful day, here in Green Bay." [As it snows in Philadelphia]
et cetera.
Damn, I thought I had a couple of good hockey lines too, but they've slipped my mind. Showing my age with most of those. And I'm sure there's a million more.
