First of all, knowledge about the city streets and various shortcuts. You really don't want to depend on a mapsoft in case of trouble. I'd think that would be Int-linked, though.
I've always called that sort of thing "Area Knowledge ____", with the blank being filled in by the region you want to cover. The bigger the region, the less benefit you get per success, of course.
Then you can specialise, either in sub-regions -
e.g. "Area Knowledge Seattle (Ork Underground +2)" - or in topics/themes, like "Bars & Nightclubs", or "Gang Territories".
Or in this case, "Shortcuts and back ways", or perhaps "Alternate routes" (make sure the GM knows that you MEAN shortcuts, back alleys, and other "nonstandard" routes, of course.

Another thing: If you are planning on modifying your own vehicles/drones, take something into that direction (I preferred "Drone Modifications"). Nothing is quite like being able to come up with your own modification plans (which specifically calls for an appropriate knowledge skill, see "Arsenal", p. 128, "The Plan").
As a GM, I would frown on just "drone modifications". For my part, I would go with an Academic knowledge, "Vehicle Engineering". Then maybe specialise, either in Drone or type of vehicle, or maybe "Engines" / "Electronics" / etc.
