This research by The Mozilla Foundation shows an appalling lack of attention to privacy and security concerns by auto makers.
I can’t decide whether is is surprising that Tesla ranked the worst. On one hand, they are (or should be) more attuned to privacy and security concerns since they are Silicon Valley oriented company. On the other hand, they seem to aggressively push the limits of technology in ways that aren’t always positive for consumers and the general public.
All of this makes makes me glad that my current car is not very smart.
