-  comment: Follows https://www.sae.org/news/2019/01/sae-updates-j3016-automated-driving-graphic
-           taxonomy. For SAE levels 3 and 4 the system is required to alert the driver before it
-           will disengage. Level 4 systems are required to reach a safe state even if a driver does
-           not take over. Only level 5 systems are required to not rely on a driver at all.
-           While level 2 systems require the driver to be monitoring the system at all times,
-           many level 2 systems, often termed "level 2.5" systems, do warn the driver shortly
-           before reaching their operational limits, therefore we also support the DISENGAGING
-           state for SAE_2.
+  description: Indicates the currently active level of driving automation according to 
+               the SAE J3016 (Taxonomy and Definitions for Terms Related to Driving Automation Systems for On-Road Motor Vehicles).
+  comment: Complies with https://www.sae.org/standards/content/j3016_202104/ and https://www.sae.org/blog/sae-j3016-update. 
+           Level 5 and 4 ADS (Automated driving system) disengage, if appropriate, only after it achieves a minimal risk condition or a driver is performing the DDT.
+           Level 3 ADS disengages either an appropriate time after issuing a request to intervene or immediately upon user request.
+           Level 2 DAS (Driving automation system) disengages immediately upon driver request. 
+           However, since many Level 2 DAS, often termed "Level 2.5", warn the driver shortly before reaching their operational limits,
+           the VSS also supports the DISENGAGING state for SAE_2.
+           Nevertheless, it should be noted that the SAE J3016 states that it is incorrect to describe driving automation features using fractional levels.
