So, how did Marty get in the car accident that ruined his life in the original time line ? He wouldn't have been near those tracks at that exact time and he wouldn't have had the new 4 by 4, OR his dad's car because it was in the shop. And without the fancy new vehicle, he'd have no reason for Needles to want to race him.
I'd say he never got into that accident in the original timeline. That outcome only springs from the changes he made, a progression of his new 1985. Though the time travel in Back to the Future is beyond wonky, none of the timelimes actually make sense when you think about them... lol!
