I am quite leery about the Internet of Things. I was leery when I first heard of GM’s OnStar. Sure it was cool that it could send you assistance with the touch of a button. And it is really awesome that it can turn the engine off if someone has stolen your car. (Especially, if it is right in front of the police who were vectored to the same location.) However, these cool features mean that GM knows every where you go and someone can shut off your engine. This is tremendous invasion of your privacy and autonomy.
I read today an article on Popular Mechanics that shows automakers do not know what they are doing and probably do not care. Be afraid.
