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

#News(General) [ via IoTGroup ]

Not only is it a popular question, but the levels of automation are also one of the largest sources of confusion about self-driving cars.
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.
The one that focuses on the automation levels for self-driving cars has the designation of J3016.
Since semi-autonomous cars require a human driver, the adoption of those types of cars won’t be markedly different than driving conventional vehicles, so I’m not going to include Level 0 to Level 3 in this discussion.
For Level 4 and Level 5 true self-driving vehicles, there won’t necessarily be a human driver involved in the driving task.
The formal definition says that there is no requirement that a human driver must be available for a Level 4 and nor for a Level 5 self-driving car.
In other words, the AI can be designed to allow for human drivers to take on the driving task while inside a Level 4 or Level 5 self-driving car, but it is vital and sacrosanct that the AI driving system for the Level 4 or Level 5 self-driving car does not expect and nor rely upon a human driver to be available to take on the driving task per se.
What does this have to do with Level 4 and Level 5 self-driving cars?
Level 5 is easy to understand, it is essentially a true self-driving car that can go anywhere and at any time, assuming that a human driver could do the same.
Level 4 is like the screwdrivers that I early mentioned, namely that for Level 4 true self-driving cars there is a scope that an automaker or self-driving tech firm can impose upon the drivability of the AI.
One automaker might make a Level 4 self-driving car that works within downtown San Francisco and only functions in sunny weather.
Thus, this particular Level 4 self-driving car won’t work when you decide to take it to say Los Angeles (which is outside the scope of San Francisco).
