the left hand does not know what the right is doing.My watch nags me constantly to get up and engage in some physical activity (I'm like, what, looking at internet porn isn't active enough, but I digress).
So anyway, having one's car do the nagging AND manipulate things such that activity is required is just another step in humanity's evolution of giving all control to our digital overlords. The final step being that we merge with our devices and become the device itself.
At which point, we'll all literally be a bunch of tools.
