NASCAR sucking the air out of the room.
I've heard about it.
The part about Danica Patrick in NASCAR hasn't come true. She signed in July with Andretti Green Racing for 2007.
David Phillips pwns CNN reporter and driver Jeff Burton:
To hear the reporter or her interview with Jeff Burton, NASCAR is boldly going where no race series has gone before [using unleaded fuel instead of leaded fuel], is so environmentally sensitive as to make the Sierra Club and Greenpeace look like fronts for the "wise use" movement.
NASCAR finally uses unleaded fuel:

Nextel Cup finally uses unleaded fuel
Blown engines help fuel unleaded concerns
Nextel Cup wondering about effect on motors after California race
By JIM PEDLEY
The Kansas City Star
In January 2005, NASCAR made one of those announcements that elicits more yawns than headlines.
Then came last week's racing at California Speedway. And suddenly, the topic of using unleaded fuel in NASCAR vehicles was burying the needle on the buzz-o-meter.
This week, in the wake of a California Nextel Cup race that featured a high number of blown engines, NASCAR observers are wondering about the effect of unleaded gasoline on the situation.
NASCAR has traditionally been exempt from provisions of the Clean Air Act of 1970, which mandated use of unleaded fuel in automobiles. But that didn't mean NASCAR was comfortable with its use of leaded gas.
Over the years, NASCAR began testing alternative racing fuels, but none were deemed usable. In 2004, NASCAR began testing an unleaded formula from Sunoco.
In January 2005, NASCAR announced the fuel showed promise and would be used beginning with the 2008 season. A year and a half later, officials said the schedule for using unleaded fuel had been accelerated.
The fuel was first used in a Busch series race last July at Gateway International Raceway near St. Louis. A couple of other Busch and Craftsman Truck series events featured the use of unleaded last year.
NASCAR took the data gathered from those races and studied it. Afterward, officials announced that unleaded fuel would be put into use full time beginning with last weekend's races at California.
In the days leading up to the race, several engine-builders talked about the potential effects of unleaded fuel on engines - and on racing.
Doug Yates, one of the most respected engine-builders in the garages, said the concern was lubrication. Leaded fuel, he said, has lubricating properties that unleaded does not.
"What we have problems with is valves and valve seats, and we've been through a very intense process of trying to find the right coatings to protect the valves from wear," Yates said. "That's one of the issues that we have, and hopefully have done our homework and we won't have any problems with those."
During the race, five cars retired because of what were listed as engine problems: one Ford, one Dodge, one Toyota and two Chevrolets.
The precise cause of the failures will not be known until the engines are taken apart and analyzed.
But Ken Schrader, who drives a Yates' powered Ford for the Wood Brothers, said: "That's very unusual for a Roush-Yates motor. They're good, dependable engines. It could be a little bit of that (unleaded fuel)."
Jack Roush, owner of Roush Fenway Racing - whose driver, Matt Kenseth, won Sunday's Auto Club 500 - went out of his way to praise the unleaded fuel after the race.
"I want to compliment Sunoco for this environmentally friendly, lead-free fuel that caused us no problem," Roush said. "We went through testing, practice and qualifying and we looked at the valve seats and inspected the engines carefully. We didn't have an issue with valve-seat recession or anything else that was a concern. From what I can see, the people that had trouble, it didn't relate to the fuel. The fuel gave us good fuel mileage and it performed admirably."
The topic of using even cleaner fuels arises in NASCAR from time to time. For example, ethanol, which is being used in the Indy Racing League.
More problems would probably ensue for the big V-8 pushrod engines in NASCAR vehicles - and would have to be solved.
But, Yates said, NASCAR engineers probably would be quite capable of solving associated problems.
"The environmentally conscious side of me," Yates said, "says that we need to be more proactive on all of these fronts, and everything takes time, but if we plan it and do our homework, we need to be leaders, not followers, in the fuel category."
"Right now our whole country is in a bit of a crisis. What the people in the stands see, they go out and usually follow suit, so if we could be leaders in that way, I would be proud to be part of that."
