Actually, it is not the first scene of the film, but it is the one that sets the story in motion. I've always found it to be a rather strange moment, as it never fully connects with the rest of the plot. There are only two elements I take away from it: first, Kyla's appearance as a witness to Diane's accident; and second, the possibility that it serves a metaphorical purpose.
