You are not disconnected from the matrix just because you suffer high noise. High noise is mostly just "higher latency". This will make it hard to play online shooters. This will make it hard to remote control a vehicle. This will make it hard to hack a Host. And it does not disconnect you from the matrix. You can still Send Messages to your drones and you can still defend against matrix attacks just fine.
SR5 p. 230 Noise:
It may seem as if traffic in the Matrix is instantaneous, but ask anyone who has played an online game with someone a few continents away—there is a noticeable delay compared to playing someone next door. When decisions are being made in the blink of an eye, every speed difference matters. The farther you are away from an icon in real life, the harder it is to communicate with it, whether your intentions are harmful or benign.
What I think you might be confused by are *Wireless Bonuses*... Basically they are some extra bonuses you can get if you connect wireless to your devices as long as you have a very fast wireless connection (think of if as if wireless connections in the world of SR5 have higher bandwidth / faster connection than wired connections). Now... if there is too much noise. Too much latency. Then you don't get the "high speed premium wifi" wireless bonus.
This is explained in the Wireless Bonuses chapter at SR5 p. 421 When they type wireless functionality in this chapter they are talking about the *wireless bonus* functionality and nothing else. Aaron clarified that this was RAI in this very forum back in 2014.
SR5 p. 421 Wireless Bonuses:
If there is a Noise Rating from a situation that is greater than the item’s Device Rating, not including distance, the item temporarily loses its wireless functionality (see Noise, p. 230).Even if you use RAW and interpret the wireless functionality in the wireless bonus chapter as if low device ratings would not only lose their wireless bonuses but actually get fully disconnected from the matrix... it still doesn't affect the rigger in your example as long as he use a
direct connection between his control rig and the vehicle;
SR5 p. 232 Direct Connections:
When you use a direct connection, you ignore all noise modifiers and modifiers due to being on different grids or the public grid.SR5 p. 266 Noise and Rigging:
If you’re rigging via wireless, all of your actions suffer
from a Noise penalty (see p. 230). If you’re using a direct connection, you don’t have to worry about Noise at all. A rigger’s data cable gets a lot of use for this reason.when directly connected to the vehicle the skills involving using that vehicle are Matrix actions, yes?
The only actions you need to take when the Auto Pilot is in control are Send Message and/or Speak/Text/Transmit Phrase. You are not really taking any actions at all when the auto pilot is in control, the pilot is. There is no test involved in Send Message or Speak/Text/Transmit Phrase. You are not affected by noise when just using Send Message or Speak/Text/Transmit Phrase. The pilot program it self is running locally in the drone and is not affected by noise.
When you are manually controlling a vehicle you are using Vehicle Actions. Vehicle Actions include Vehicle Control tests, Gunnery tests and Sensor tests. You are not affected by matrix noise when manually controlling a vehicle.
You are using Matrix Actions when you are remote controlling a vehicle (mostly Control Device). Your actions are limited by the normal attribute or the data processing matrix attribute of the device you first formed your persona on, whichever is lowest. You
are affected by noise when remote controlling a vehicle.
When you are jumped in with a control rig you are also using Vehicle Actions, but when jumped in you get to treat vehicle actions like matrix actions. For example, your vehicle actions get a positive dice pool modifier for hot-sim. You are affected by noise if you jumped in via remote and not affected by noise if you connect directly.
The idea that Matrix Actions require Matrix connection is asinine.
SR5 p. 237 Matrix Actions
Matrix actions are only available in the Matrix.Xenon's reading is very intriguing to me, in saying that being Jumped In (and presumably, driving said vehicle) might not necessarily be Matrix Actions in the first place.
"Logging into the matrix" is not a matrix action (you are not logged into the matrix yet, you need to be connected to the matrix to perform matrix actions). You can form your persona on a commlink, cyberdeck, rcc (with the Change Device Mode action) or by directly jumping into a vehicle with a rigger interface (with the Rigger Jump In action).
If a decker with a control rig want to jump into a hostile drone with his persona formed on his cyberdeck he need 3 marks and take the Matrix Action Jump Into Rigged Device.
If a rigger want to jump into one of his drones with his persona formed on his commlink or RCC then he need to take the Matrix Action Jump Into Rigged Device.
Vehicle Actions are not Matrix Actions, but when jumped in they are treated as Matrix Actions.
