NASCAR will crack down on aggressive driving at Dega

NASCAR plans to crack down on aggressive driving and bump drafting beginning with Sunday's Sprint Cup race at Talladega Superspeedway, particularly regarding two-car breakaways that have become commonplace with the new car. Track officials hope they got the attention of drivers when they parked Michael Waltrip for pushing Jimmie Johnson's car through the corners during Friday's second practice. "It at least sent a good point of conversation out there in the Motorhome 500 lot,'' series director John Darby said after Saturday's qualifying was rained out. The new car has presented a problem because two cars that match up well are able to pull away from the pack. ESPN.com
