I believe most 50s models (for example) counted miles traveled in reverse as "normal" miles, i.e. if your odometer read 100 miles, and you drove backwards for 10 miles, it would come back reading 110. Now, in the early 60s (with mechanical worm gear odometers) I know that there were lots of complaints about "odometer fraud" (hook up a drill, go to town!), so somewhere in here is the turning point. As soon as cars started using ECUs, though (1980/81+ for GM, I think), magnets created the signals that actuated the odometer. And without getting into it too deeply, magnets don't care if you induce current forwards or backwards, so no rollback is possible.
I guess I assumed that most people aren't driving anything that pre-dates Roy's first Cup win with the Habs.
