I don't see how this comment ties to the parent comment in any way? What part of their comment are you referring to?
My Model 3 didn't have an alarm system or dashcam when I purchased it in November of 2018. I got that later as an OTA update. How many vehicles can do things like that even today in 2019? Precious few that aren't Teslas, mainly due to dealer network legalese. They wanted us to bring our Ford Fiesta into the dealer for them to load a new version of Sync on it via a thumbdrive. Such silliness.
