From what I could gather from the terms and condition of the Connected Drive your car also uploads details of your journey time which in turn updates the RTTI. I'm not sure if this is the same database that the portable nav systems (TomTom, Garmin, etc) use and whether they contribute to the information but I have found it to be super accurate on my ProNav system.
On a recent trip from Newcastle to Leicester the quick option took my on the A1(M) then off on to the A614, A6097 & A46 rather than the M18 & M1... I'm guessing it made the decision on the back of RTTI as the arrival estimate was bang on...
