NHTSAs Coming Backup Camera Mandate

According to Automotive News, the NHTSA is going to announce a backup camera mandate to try to reduce injuries from drivers backing over pedestrians.  

I am not in favor of this mandate, because it will hurt vehicle affordability by increasing prices.  Expect the systems to add around $200/vehicle in cost.  

I think it would be better to allow automakers to install an ultrasonic system, which would give an audible and text warning, as a way to offer the benefit in a low cost package.

There would be a side benefit.  All new cars would come with LCD screens, which should allow for higher end infotainment displays on low end models.
