Looks like I spoke too soon on Toyota. It appears the fix to their problems may require more than a metal shim. There may be problems with the drive by wire and braking software, which is a lot more complicated than a piece of metal.
Still, I have to question the driving skill of people who experience the issue. Why can't they just put the car in neutral? Or as a very last resort, turn off the car and use the emergency brake? What other distractions are going on in the car when the issue occurs?
