At this time there are no features of V9 specific to having FSD activated.i haven't gotten the update yet and am not in a hurry given the elimination of the split screen.
a question for any *paid* FSD option owners out there - does V9 w/ paid FSD get you anything over non-paid-FSD optioned cars (i realize all the cars after a certain date come with the FSD *hardware*, but wondering if you paid for FSD if you now get something new from the V9 update)
