I have an interesting experience I'd like to share which is possibly relevant to this thread.
My particular ZS EV Trophy Connect Long Range has a software bug with the navigation - I seem to get other people's home/work settings and also their recent destinations.
NOTE #1: I use CarPlay most of the time so this doesn't bother me much, but in context - this bug of mine may reveal interesting information on MG.
NOTE #2: I have informed my dealer twice about this issue and mentioned the words "Data Leak" clearly both times, but they didn't seem too bothered.
So, whatever home/work point is set to, or if I clear my recent destinations - the car always seems to have different addresses when I get back to it the next day.
First I thought it was in some sort of Demo mode, but the addresses are international (France, Germany, Thailand, UK, etc) - and some are business names, some are just post codes, some are full addresses - they seem genuine. I considered driving up to a UK address and see if they have an MG, but so far they've all been a bit too far for me to visit.
My current conclusions are:
#1 - MG's servers are collecting all destinations entered by some of their cars - globally - which doesn't seem appropriate to me. I can fully understand collecting anonymous data on car performance - but your home address doesn't seem very anonymous.
#2 - MG's servers are somehow re-filling my car with all that data, implying that they have the ability to do so, and thus can remotely change navigation data - again, doesn't seem right to me. The navigation should be 100% locally run, and only require traffic updates.
I could, of course, be completely wrong and my car truly is in "demo mode" but I can't find such a setting anywhere, my dealers don't seem to know anything about it, and last time I checked, nobody on the forum had mentioned anything like this either...
Any thoughts?
PS - the data may also easily come from non-EV MG cars - this is more of an MG thing, rather than an EV thing.
