Scott Dixon, Ganassi, Indianapolis 2012Scott Dixon is optimistic that slower traffic will not be a problem in Sunday's Indianapolis 500, despite the horsepower deficit that the two Lotus-powered entries have experienced compared to their Chevrolet and Honda-engined rivals.

Lotus-equipped Simona de Silvestro and Jean Alesi qualified at the rear of the field with lap times more than 16mph slower than that of polesitter Ryan Briscoe, but Dixon is hopeful that the slower cars can be navigated safely.

"I think the biggest thing when you come up on traffic is making sure that they do the same thing every time," said the Honda-powered Ganassi driver, who won the race in 2008. "You can't get out of the way here, but if we know what they're doing... and one of us could be in the same situation; if you have a bad car and you're struggling and the car's loose.

"It's just when the target keeps moving, it's hard to predict where they're going to go. But they're all good drivers and we know each other well enough to know what to expect.

"Sometimes it's easier to pass cars that are a lot slower. It's just how and when you get to them; whether it's right in the middle of the corner and you check up the whole train or whatever it is that it's difficult."
