Could restrictor plate tracks go back to time trials?

With Sunday's knockout qualifying session for the Daytona 500 proving chaotic, as with last fall at Talladega, many people are calling for NASCAR to either bring a return to single-car time trials at the four annual restrictor plate events at Daytona and Talladega, or make significant changes to knockout qualifying at these tracks. Others are arguing that time trials should be brought back at all oval tracks, because they feel group knockout qualifying, a staple in some open-wheel series for many years, only truly works at road courses, which some racing series race on almost exclusively. NASCAR has reportedly said it is studying possible changes to the qualifying format at Daytona and Talladega, although it's unlikely they will revert back to time trial qualifying at these tracks.
