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

Hi @caribouW3, @tguild,

The explainer is very high level and provides useful background, but I'm struggling to understand from it what the specs actually do. I also can't see any user needs articulated. What changes/benefits/risks for the driver/user of a car with this work in the ecosystem? Additional pointers on what changes for developers of apps for vehicles, and vehicle manufacturers/distributors would also be helpful. If you could update the explainer to start with clear user needs, and include an outline of the actual functionality of the specs, how the two specs relate to each other, as well as indication of why you have made the design choices you have and what alternatives were considered, that would be really helpful.

Also could you provide a list of the key differences between version 1 and this update, as well as any information on how you addressed feedback from the [previous TAG review](https://github.com/w3ctag/design-reviews/issues/234) in the new version? I can't see a changelog in either of the specs.

I appreciate the challenges in filling in the Security & Privacy questionnaire, however I'd like to request that the editors/WG members read through it and complete the questions that are most relevant, and note why any questions you can't answer are not applicable. I can see the [Privacy section in the Best Practices document](https://www.w3.org/community/autowebplatform/wiki/Best_Practices#Privacy) is very short and appears to be unfinished.

I have had an initial look at the specifications themselves, and can see that the [HTTPS section in VISS2 Transport](https://www.w3.org/TR/viss2-transport/#https) appears unfinished. Do you have links to issues or discussions about this? What is the plan for this section?

As vehicles are so ubiquitous in society, and for many millions of people essential for meeting basic needs, this work potentially has an enormous global impact. When WG members have some time, I think it would be a very useful exercise to work through the [draft Societal Impacts questionnaire](https://w3ctag.github.io/societal-impact-questionnaire/) to think about the potential impacts in the wider ecosystem. This is a draft document that is not a formal part of the TAG review process, but I find it particularly relevant in the case of this work, especially if you are struggling with the Security & Privacy questionnaire.

I'll be happy to carry out a more thorough review as soon as possible, and an updated explainer and Security & Privacy questionnaire would be a great help. Thanks!
