Exactly this. Many people pay little to no attention when they operate a vehicle. When you get a car serviced, for instance, the lights are always shut off. People never notice it was done, and their interior has lights, so... Canada has legislation introduced that would make lights default to auto to prevent this, but I'm not sure where that is at the moment. If it passes there, I suspect many manufacturers will adopt it to keep all North American market stuff the same.
