Just living through Monday's crash at Daytona International Speedway would've been hard to believe, but NASCAR driver Austin Dillon actually walked away from it.
"It's pretty amazing," said Dillon.
The catch fence prevented tragedy, but 13 fans suffered minor injuries from flying debris.
"We are all over that to understand what happened," said Brian France, CEO of NASCAR, to Sirius Satellite Radio.
According to the Charlotte Observer, at least 46 spectators have died watching races in the U.S. from 1990 to 2010.
Three died in 1999 when a wreck launched a tire into the stands at the Charlotte Motor Speedway.
Humpy Wheeler was the track president at the time.
"This scares the daylights out of everybody that operates a racetrack," said Wheeler. "This is something that we're all concerned about because we know that could, if it was bad enough, wipe you out of business."
After the crash in Charlotte -- and another in Detroit -- stronger, thicker cables were installed in fences that were then raised 16 feet higher. Wheeler expects similar evolution after Monday's crash.
"What it didn't keep out of the grandstand was the shrapnel and that's the thing that I think the industry is going to be attacking with a vengeance right now," said Wheeler.
Wheeler says a giant solid, see-through barrier could be installed at race tracks to block debris, just like the ones at hockey games that keep pucks from flying into the stands.
