The federal government is now contemplating making back-up cameras mandatory on all new vehicles. Parents sometimes back their cars over their children who are permitted to run any damn place they want to, so as to avoid stifling their little emotional developments.
Well, you have to look, don't you? If you are backing up, you have to look in your mirrors, or swivel around and look out the back window, or something. Right? After all, the lady who backed her SUV into my car down in the basement parking lot had a back-up camera in her car. She didn't look at it.
Not everybody pays attention to what they are doing. Not everybody looks; they merely trust the way is clear.
For this reason the original proposal was that reverse gear just be eliminated from all passenger vehicles, altogether. And it would have passed, too, except that the bureaucrats couldn't figure out whether to make circular driveways or solar-panel powered roundtables required features in all urban areas, so they compromised. They'll revive the reverse-gear elimination proposal after all cars are finally equipped with back-up cameras.
It's for the children.
