It’s not ‘when’ it’s ‘if’. And let’s be honest here, if you get into an accident, someone else is already calling 911 as well.
So in exchange for being spied, your data sold to third parties (likely), and knowing every place you visit at every time and know your movement patterns better than anyone, you get the protection of someone calling you, (if it’s a serious accident you’re probably not answering and if you’re answering, you can probably dial a cellphone. At least 9/10 of the 1/100000 chances of a serious accident).
Just curious if the trade off is still worth it for you? I don’t know, I know I don’t.
