I've had a memory echoing around in my head from something I saw on the TV when I was about six, where the first scene featured a guy (the main character) saying goodbye to his wife and son as they drive off school, only to see them die in a firey car crash about a minute later.  The rest is kind of a blur, but the end is a replay of that scene except this time the guy suddenly realises what will happen and stops and saves them.  Any ideas?

That movie is Timestalkers which starred William Devane, Lauren Hutton, and Klaus Kinski.
