Getting back to the OPs original topic, I would, again, remind folks that AI Traffic is simply a filler. It has no bearing on real world traffic and is nothing but a way to put fictional traffic into the sky. LIVE Traffic is the improved next generation addition to MSFS.
As the algorithms are improved to compensate for the shortcomings of the available flight plan data that the system uses, the density of real world traffic is being improved. Eventually we will be seeing exactly what we are meant to see when flying through the simulated real world skies.
