Imagine a world in which your car tracks everywhere you go. Over a period of time, it builds up a database of your driving habits, how long you stay at particular kinds of dining places, entertainment places (ahem!) , and the days, and times you do it. You can no longer go to massage parlours without your data being checked by your car software admin (read – your home admin)
And that data is mined using machine learning algols to give you better ads for pizzas, or a reminder for food after every 3 hours , or an ad for beer every Thursday after 8 pm .
Welcome Brave New World!
