I was fascinated to learn that Volvo wants to make cars that can effectively spy on their drivers, psychoanalyse what he or she is like and then alter its mechanical performance accordingly.

Reading the official bumpf it is all very helpful because "this will enable the driver to be able to rely a bit more on their car, and know that it will help them when needed," explained Per Landfors, engineer at Volvo Cars and project leader for driver support functions.

By placing a sensor on the dashboard to monitor aspects such as in which direction the driver is looking, how open their eyes are, as well as their head position and angle, it is possible to develop precise safety systems that detect the driver's state and are able to adjust the car accordingly. This also means that the car will ensure that it does not stray out of the lane or get too close to the car in front when the driver is not paying attention, as well as being able to wake a driver who is falling asleep.
