FILE - In this Sept. 1, 2012, file photo, Mike Conway, of England, drives his car during IZOD IndyCar qualifying for the Grand Prix of Baltimore auto race in Baltimore. Conway doesn't want to give up IndyCar outright, and if he could find a team willing to let him run just road and street courses he would jump at the opportunity. Right now, the only opportunity came from Rahal Letterman Lanigan Racing, which will field a third car Sunday at Long Beach for Conway. (AP Photo/Nick Wass, File)
