Well good. Every little step makes that difference.
In our neck of the woods, new laws are coming in such that no new car can be sold that does not have stability control, brake force distribution and ABS.
The next one around the corner might just be the law that dictates the minimum number of airbags and where.
If everyone has to get on board to sell product they can't sell safety as an option, or offer it only on the 'premium' brands, as if to say the lives of people that earn less are worth less.

Why only vehicles under 10,000 lbs? You can see our the back of those! Is those over that weight they should be worrying about!

Good point. Not only is it necessary to cover the rear of the vehicle, but also the side, especially for commercial vehicles when entering a main road at a shallow angle. The rear view mirror does not exist and the side mirrors all too often do not cover the main road enough to let the driver know when it is safe to exit the side road.
The need for better all-round visibility on large vehicles is all the more important for vehicles whose base country drives on the opposite side of the road e.g. Mainland European vehicles driving in the U.K. and vice versa.

They shoud have automated view change in rear view mirror. Not sure why only smaller vehicles, I guess, people driving those have the most deaths occurences? Also, add the audible and then we are all safe??

Ok. I'm all for saving lives but this government nanny stuff is getting old. How many people were killed last year by backing vehicles? Maybe 15 or 20? Why not proximity alarms that many cars already have on rear bumpers. Nooo, let's jack up the price of a new car by 1000 dollars for a rear mount camera and a dash monitor. Wonder what GOP or Dem Congressmen are secret stockholders in companies that make those camera systems? The Feds are completely into our private lives now. And that is NOT good!

Human drivers cause accidents through inattention, texting, drinking, and speeding to mention a few. Robots mandated to replace human drivers by 2025 says NHTSA.

@edro: please read the article before posting. "210 fatalities and over 15,000 injuries" per year. Also, from another article ( http://money.cnn.com/2014/03/31/autos/rear-facing-cameras/index.html ) on this, the estimate was $140 per camera system.
Also of note is the property damage (not mentioned by either article) that is caused yearly by people who have trouble reading their mirrors while backing up.

Esp for SUVs, midsize on up alone, almost got into accident since I couldn't see my rear.

I'd rather see them require better rear and side visibility.

and these camera and display systems are going to last 150 to 200 thousand miles? I don't think so.....
