The point was that the setting is based upon time, not distance. For example, each increment represents a half-second worth of following distance (I don't know the actual amount of time, as I am awaiting delivery of my Model S). Two seconds of following distance at 70 mph is way more distance than at 35 mph.
Each one is one second. So between 1 second and 7 seconds. Otherwise you are entirely correct. I adjust my following distances based on local vs. highway. For example, on my recent very long road trip (1600 mi round trip), I set it at between 5-7. In heavy traffic for my commute, I set to 1 to avoid inviting people to cut in (which AP handles better but still not ideal). On local roads, I prefer 2 and normal highway commute is 3-4.
I feel the latest FW operates better with more daylight between my car and the lead car (can see more lane lines and better path plan).
