It's kind of tough to comment accurately on specifics of a system that is evolving. Some portions, put on hold while being worked out, etc. I will say that we should all be on the same page, in terms of communicating the policy. We stay tuned...
Clearly, Southerntrucker, you are mistaken in stating that 2 seconds headway qualifies as "tailgating". That is nonsense. It may violate policy and trigger an event, but is not even close to rising to the level of tailgating, or aggressive driving.
One element that is unquestionably good, is the video evidence that so called "ghost braking" is real, despite vendor assurances to the contrary.
