FILE - In this Feb. 20, 2011, file photo, Dale Earnhardt Jr. (88) and Martin Truex Jr. (56) team up during the Daytona 500 NASCAR auto race at Daytona International Speedway in Daytona Beach, Fla. Two-car tandems took over the season-opening Daytona 500, where the huge pack of cars broke apart as drivers realized that the fastest way around the superspeedway was with just one partner. Two drivers hooked up, took turns pushing each other to the front, then swapped the lead when their engines got too hot from all that pushing. Many fans fear a repeat of that racing at Talladega, and by every indication, that's exactly what they'll see. (AP Photo/Lynne Sladky, File)
