There have been comments about Autovista featuring only "select" cars.
From one of Dan's interviews:
"...every car that was selected for Autovista mode was
selected based on its unique tour that it was gonna give you..."
It stands to reason... all of those details, plus voice-over narrations...
Like the rest of us, we just need to wait for more information from Turn 10 as we get closer to release.
