Abstract
A feature for a motor vehicle that includes a navigation system and one or more safety systems that detect an area around the vehicle. The navigation system uses geographic data and the one or more safety systems also use geographic data. The feature advises the vehicle driver to travel along roads that are represented by data that enables operation of the one or more safety systems. According to one embodiment, when the navigation system is requested to calculate a route to a destination, the navigation system favors roads that are represented by geographic data that enables operation of the one or more of the safety systems. According to another embodiment, the feature is implemented interactively, while the vehicle is being driven, by indicating which paths ahead of the vehicle are favored as being represented by data that enables operation of the one or more safety systems. According to yet another embodiment, the feature is implemented heuristically to advise the driver of alternative routes to commonly visited destinations wherein the alternative routes favor roads represented by data that enable use of the one or more safety systems.
