Just noticed the edit to Reply#8:
... nothing Honda can use is not what they already know or could easily find out anyway, I am not sure what personal data you think it can give them, as I have stated before in the settings you can choose what information you wish to be transmitted or even disable it ...
“Personal data” is any data that can be associated with an individual. Section 1 of the Privacy Policy (Annex 1 of the Ts&Cs) defines the data Honda collects, and tells you that it can be associated with you as an individual when aggregated with other records (eg they know the identity of the individual who owns the car with that VIN). So they correctly define the whole lot as Personal Data (see 1.3). And none of the stuff about car performance, driving style, location, etc, is available to Honda through any other means so your assertion that they already know it all anyway is not correct.
Once again you are completely ignoring that you can control what is sent and collected by Honda and you can just allow what information if any you want to be collected by them while still using several of the useful features of the app.
No, I didn’t ignore that comment, which is why I said ...
... if you’re going to turn it off, why have it in the first place ?
But the main point here is that having this system or not is an individual choice based on personal attitudes and values. As I’ve said several times now, anyone making that choice needs to understand the implications for their personal privacy, and that is important to many people which is why I’m highlighting it. That is not criticising anyone else’s choice.
Incidentally, I see the Ts&Cs & FAQs have been amended since the last time I looked to prevent you receiving someone else’s personal data after you’ve sold the car. That’s a step in the right direction, although it can take up to 6 months to kick in.
