Would you be happy with 24 hour monitoring of where you go in your car. And its not just about knowing when you cook your dinner its what time you get up, when you go to work and return, how many people are in your house the sex of the people in your house, what you watch on tv, when you go to bed, when you get up, when you go on holiday, when you get back.
My car, does already track, and video every journey it makes. The census plus other departments, already know age and sexes in my home, already.
