Edit: to clarify: the message in the ad is actually ironic/satirical, mocking the advice for cyclists to wear high-viz at night.
It uses the same logic but inverts the parts and responsabilities, by suggesting to motorists (not cyclists) to apply bright paint on their cars.
So this ad is not pro or against high-viz, it’s against victim blaming

IIRC there was only a short window when turning the rear lights off was a thing, and the law has since gone back to having to turn them on when the car is turned on. While there are still people in cars like that, they’re a minority.
