Autonomous car levels

There are 2 systems of classification for autonomous cars prevalent today: National Highway Safety Administration (NHTSA) and Society of Automotive Engineers (SAE).

A good article illustrating the various levels is here - https://jalopnik.com/whats-a-level-4-autonomous-car-this-chart-explains-eve-1785466324

Ruminating on POC vs. POV

Of-late, it has become a fad to label any pilot project as a POV (Proof of Value), rather than a POC (Proof of Concept). But, is there a real difference between POV and POC?
Jotting down my views below:

• A POC is typically an internal project and is not exposed to the real end consumer. The objective of an POC is to validate if the technology works or if a concept is viable.
• POCs can be used to explore emerging technologies and share knowledge within the team. POCs also help teams come up with more accurate estimation of stories. 
• Thus a POC will prove that the technology works, but will it deliver the promised business value to the enterprise? 
• A POV will prove the business value of a concept - it can be in terms of increased ROI, lower TCO, faster GTM or increased customer satisfaction. If these factors can be measured, then you are delivering a POV !
