I have read a couple of reviews that have a different take on this film. The central issue is the story that Alvin tells the young pregnant girl about Rose's children. He says, "Someone else was supposed to be watchin' them, and there was a fire, and her second boy got burned real bad."
One article argues that Alvin's vague references—"someone else" — and passive constructions — "there was a fire" and "got burned" — imply that he was the "someone else" who let Rose's children get hurt and then get taken from her.
The article says another clue is the burning house that appears in the background as Alvin flies down the hill. "This scene functions as a flashback to the earlier fire, the one in which Alvin's grandchildren were burned. Alvin's face, bathed in sweat and flickering orange with firelight, and his eyes, bulging and rolling in his head like a frightened animal's, express a terror that transcends his immediate situation. When intercut with those quick, jarring shots of the blazing house. The real object of that terror is unmistakable. Alvin is the unnamed 'someone' who was supposed to be watching Rose's kids. He let his grandson get burned. He caused his daughter's children to be taken away by the state. After he manages to stop his tractor, he sits panting and shaking in terror, staring at nothing, the burning house clearly framed in the background. He is trembling not just in reaction to his near-accident, but in an abreaction to that original trauma — another time when Alvin Straight lost control and events took on their own scary, unstoppable momentum."
It's a really long article, so I won't list all its points here, but it basically argues that everything on the journey, from the deer woman to the WWII vet, comes back to Alvin's role in the fire.
So, what do you think? Is this reading things into the story that just aren't there? Or is it a plausible reading?
