Recently I have noticed cars in parking lots with their reverse lights on even when the driver is not behind the wheel. I stop to let the drivers back out, and then realize they have no such intention. I don't know what that signal is telling me.
On cars with this feature, in what situations do the reverse lights come on?
What is the purpose of this feature?
Has this feature been implemented pursuant to a government regulation, a recommendation from an industry body, or some other published source? (I have searched, but found nothing.)
If there is a white paper or something for this feature, does it discuss the possibility that drivers may begin to ignore reverse lights?
