Vision could be a problem in tight packs at Talladega (cont'd)

Two-time defending champion Jimmie Johnson agreed with Biffle that the wing causes problems, but he said he isn't sure it can be fixed. He said that he questions whether some sort of clear wicker "bill" is going to make any difference.

"I don't think that wicker bill is going to make any difference at all," Johnson said. "There are a couple of things. One, the angle of the back glass is set in a way where it reflects a lot of light and you can't see in the car in front of you. It's almost as if there is a mirror of some sort there.

"So the wing does pose a problem, but that quarter-inch or half-inch of wicker isn't going to make things better. The other part is, waving out of the side of the car. The greenhouse on the vehicle is so large that you can't see around the seatposts of the car in front of you to see where the window net is -- because the window net is in-board. And you can't see a guy's fingers or his hand or whatever. There is very little room to reach out.

"It's a problem and it's the same for all of us. We just have to be very smart with the spotters and how the spotters communicate to each other up there, to let them know when somebody is going to pit."

Officials from NASCAR said that they have been working on improvements.

"The teams have done a pretty good job of working through this by shifting around their rearview mirror angles," spokesman Kerry Tharp said. "And we've looked at various materials for the wing that could possibly help alleviate the situation some."

Biffle, however, insisted that it could be -- and should be -- better. He also said that the lack of ability to see in the cockpit of the car in front of him contributed to an accident he was involved in at Talladega last fall.

"It happened to me here. I got spun out. I got shoved into the back of Carl [Edwards] coming off Turn 4," Biffle said. "It's was a simple little deal. Nobody got damaged, thank goodness. But it was a fact that I couldn't see him slowing up, or I couldn't see him waving his hand or anything else.

"They've made the promise to us for 12 months that they were going to work on it. And I don't see it on the car yet."
