I’ve seen a number of such cars, and so far the only thing in common: they are American “big three” products.
Other than confusing drivers with allowing for headlights to be on with no other lights, the other dangerous thing they introduced was using the backup lights as “convenience lighting”, where car would have backup lights on for some time after is was shut down or after owner opened the door.
As a result, nobody seems to pay attention to backup lights anymore, so even if you are legitimately backing up, some cars run across next to you and pay no attention.
I’m shocked at these vehicles to be allowed on the public roads, but seems that neither oversight agencies, not politicians pay attention.
