I'm not defending
@Zorba's position, however, must call out BS when I see it.
As far as I can tell, NO ONE with a backup camera can get even close to this, unless by pure luck. More people appear to be backing into spaces nowadays (because of the cameras), yet it would seem the camera does them little good. Parking jobs are obviously worse...and that camera would seem to do little to help one center their vehicle in the space laterally, which is typically the bigger issue.
I'm sure someone here will argue they can, I would counter that it's unlikely unless you also have proximity sensors. You need to know the physical bounds of your vehicle, and most people have no clue. I know some old salts that could backup a 53' trailer with mirrors more precisely than 99% of people with backup cameras on their Kia SUV, because they are aware of the extents of the mass they are operating. All this stuff is simply compensation for people not using what's already available (eyes, brain, mirrors) because they just can't be bothered...and that's why self-driving cars are even a thing, and why I suspect someday will be mandatory as well.
I don't think cameras should be mandated. Mirrors always work, provided you use them. Of course, if you're too lazy to clear the snow off your car, teats on a boar hog would be more useful than either option...
