I am sure this article has been shared before, however I wanted to have a look at this topic.
The articles short summary is this:

All 25 car brands we researched earned our *Privacy Not Included warning label – making cars the worst category of products that we have ever reviewed

I am currently driving a 2014 Ford Fiesta which just has a radio with a CD player and Bluetooth. I do not need more than that in a car.

The reason I am looking at all is that that the Fiesta does not belong to me and the friend owning it will be moving out in a bit, so I kinda need another one.

There seems to be one brand that is not as bad as the other ones (but still bad): Renault; mozilla's review...
Maybe I will have a look at their cars.

What do you guys think? Stick to older used cars and not use an EV or look at which of the manufacturers have the least bad privacy policy?
