The manufacturers did not want to have to build these into every car, they wanted to keep charging a premium for it.
8,000 people in the US die every day -- that's as regular as you can get.
Children dying from a vehicle backing over them is _rare_. Obviously, any death or injury is awful, but we're never going to get the number to zero.
The fear of backovers is much greater than the reality.

I think it's quite the reverse: now they can pocket that money from every car.
Why would they not want to make yesterday's premium option into today's standard non-option?
You know, the reason so few children die from backover is maybe due to people fearing it?
In general or in those stupid, oversized trucks/SUVs with utterly poor visibility?
Which popularity is due to Corporate Average Fuel Economy?
That being said, I'd take large European mirrors that know to go down when car is put in reverse and basic sensor over this any day.
(though, I'm now in Chile and amount of huge cars/SUVs/trucks/pick-ups on the street is simply mind-boggling... whhhhyyyy on earth one would drive this monstrosity in the city?!)
