New technology helps drivers navigate traffic to decrease driving stress

Volvo is taking the next step toward building a completely autonomous car by developing a new vehicle-control system that works like cruise control in low-speed stop-and-go commuting.
This so-called traffic jam assistance feature works with existing adaptive cruise control and lane-keeping technology, manipulating a car’s accelerator, brakes and steering to automatically maintain a set distance from the traffic ahead while keeping the vehicle within the current lane at speeds under 30 mph… 
The system is expected to go into production in 2014
