[w3ctag/design-reviews] VISS (Vehicle Information Service Specification) 2 Core and VISS 2 Transport (Issue #768)

Wotcher TAG!

I'm requesting a TAG review of VISS 2 specifications.

[One paragraph summary of idea, ideally copy-pasted from Explainer introduction]

VISS is specifying a means to access vehicle signals data in a standardized way. The Data model is 
defined in another specification (VSS, jointly developed by W3C and COVESA).


  - Explainer¹ (minimally containing user needs and example code): https://github.com/w3c/automotive/blob/gh-pages/viss2-explainer.md

  - Specification URL:  https://www.w3.org/TR/viss2-core/ and https://www.w3.org/TR/viss2-transport/

  - Tests: [wpt folder(s), if available] None
  - User research: [url to public summary/results of research]  N/A
  - Security and Privacy self-review²: 
  The scope of this specification is narrow and does not describe a specific data model (VSS does describe such a model).
That makes it rather difficult to analyze the privacy risks (in particular identify the information that could be particularly
sensitive, although PII is not the core of data like what VSS describes). The WG and CG have also worked on best practices
(https://www.w3.org/community/autowebplatform/wiki/Best_Practices). VISS 2 has improved on security and privacy thanks
to the access control features of the protocol (see https://www.w3.org/TR/viss2-core/#access-control-model).
The WG has also started studying other privacy-improving techniques like geofencing but it is clearly out-of-scope for these
specifications.

  - Primary contacts (and their relationship to the specification):
      - Carine Bournez (caribouW3), W3C staff
      - Ted Guild (tguild), Geotab, WG Chair
  - Organization(s)/project(s) driving the specification:  W3C Automotive WG, COVESA
  - Key pieces of existing multi-stakeholder review or discussion of this specification:
  - External status/issue trackers for this specification (publicly visible, e.g. Chrome Status):
