Approaches are described for utilizing a combination of location determining and tracking techniques to attempt to provide driver assistance under a variety of different circumstances, such as location assistance to locate or get back to a particular object or location, and visual and/or audible assistance to alert a driver of potential danger. For example, a driver assistance system can be provided that can monitor traffic conditions as well as attentiveness of a driver using a portable computing device (such as a mobile phone) to provide visual and/or audible notifications to alert the driver to potential dangers and/or take defensive action. The driver assistance system can further be used to automatically determine the location of a user's parked automobile and provide assistance, such as directions, to get back to the location where the user parked his or her automobile.
