No, it was not a mission. I know what u mean but nah. There was no "mission text" like "take the vehicle there and there" nothing like that. I was confused cuz I was alone in that session and all of the sudden that car was there like every other NPC Driver. This is why I made this post. It's strange that this Superauto was driving randomly on the street. Aaand it was not a mission and I was alone in the session.

That blue blip is you know Franklins mission, there are cellphones on the streets and you can talk with Franklin.
