Will concrete surface catch drivers out?

All practice for standing starts to date by Champ Car drivers have been done on asphalt. On Sunday they will be starting on the concrete runway of the Burke Lakefront airport. Concrete of course has a different coefficient of friction than asphalt so wheelspin could be an issue.

"I don't think it's actually concrete. It's asphalt, too. It's just white asphalt," said Bourdais at the post-qualifying press conference. "The big difference is that it's grooved asphalt because of the runway. Yeah, it's interesting. We practice in pit lane where it's nice and new tarmac. Then you go on the racetrack, it's striped and everything. It's going to be a little tough to anticipate what kind of grip we're going to get."

Any chance to do that in morning warm-up?

"We can always bring it up and see what happens," said Bourdais
