Bobby Labonte on restrictor plate racing:

"That type of racing to me isn't as exciting as going 200 miles per hour at
the end of the straightaway at Atlanta (which does not use restrictor
plates) because I can control what I'm doing," said defending series
champion Bobby Labonte.

"I have the opportunity to let off the gas and hit the brake and all that
stuff. At Daytona you don't do that. You just hold it wide open, and then
you're in a pack of cars all day. It's obvious that's not the same type of
racing we're doing everywhere else. It's not the same."

I guess you know more about racing than Bobby Labonte?

There's only a few times you ever use brakes during restrictor plate racing-

1) To avoid an accident
2) To slow down while entering the pits
3) To slow down in the turns due to a handling/mechanical problem with the
car.
