AVONDALE, Ariz. (AP) -- Trying to kill time while the Daytona 500 was delayed by an inferno, Brad Keselowski started tweeting from his car, then on the track.
By the end of the night, after providing updates, posting photos and answering questions from fans, Keselowski's followers had ballooned from 65,000 to 200,000.
With a few pecks of a tiny keyboard, Keselowski had become a Twitter sensation, a NASCAR innovator and the central figure in a debate about whether cellphones should be allowed in the cars.
NASCAR said on Tuesday it had no problem with Keselowski having a phone in his car or his tweeting. Some drivers were concerned that others might take it too far or gain a competitive advantage by having a smartphone in their cars.
Keselowski says he plans to keep tweeting.
