Explaining Level 4 And Level 5 Of Self-Driving Cars In Plain English

People often have generally heard about the levels of self-driving cars and yet are unsure of what each of the levels designates.

The media frequently makes things worse by misstating the nature of the levels, or by using the levels in misleading ways that are not in keeping with the proper definition of the levels. Sadly, sometimes a fake news article about self-driving cars will pretend that there is no formal definition of the levels or decide to make-up their own definition entirely.
