@Sichr "Just a remark: Once you track the node, you need to use Analyze it (Matrix perception) to find its Acces ID...but Im not sura about that, you can red something like that in the short story at the beginning of The wireless world chapter in SRA

Not according to

With giving Zach's bike the all clear, I mean that if/when the Drone scans Zach, I'll make it believe it scanned it and cleared it.
Again, not sure that's possible, but I'm guessing the drone has a list of vehicles it's supposed to check, marked with either "unchecked", "checked: ok" and "checked: illegal". Wagner's just trying to mark themselves (and possibly Zach too, if he's on the checklist), on the "checked: ok" list.
Being spotted in the vehicle: I thought it was pretty standard for all windows being one-way see through in 2072. Wagner definitely doesn't want people to watch inside.
