Tape won't undo all the other changes to cars that OEMs engaged in once they were required to have a screen.
Congratulations. Your pet regulatory change has reduced back over deaths by under a hundred a year. In a vacuum with spherical cow that's great but reality isn't a vacuum with spherical cows. And now that you've put this hardware in cars and engineers have taken advantage of it you've increased back out accidents and merging accidents (both are inversely correlated with rear visibility) and you've made many of the critical 2nd order functions of operating a car less intuitive and more distracting to use. You've but you don't care about that because the metric you were gaming (back over deaths) is marginally improved. And when called out by people who want to look at the big picture you respond with insults. Screw you and the safety vest you rode in on.
