Are you attentive on the road? Do you look straight ahead? If you have a habit of watching the sides instead of the way ahead there is a car nanny created for you. The smart device tracks the direction of your look and reminds you of driving your car carefully and keeping attention on the traffic. It is being done with a flash first, later, if no attention is payed to it, it blocks the control screen.
I think it is a wonderful invention, made to save lives on the driveway. Hopefully it can rise the attentiveness of the drivers, especially if they have kids in their car, leading to less accidents. If you are interested in more details you can read about the nanny car here.
