Road Sign Information (RSI) – limitations
RSI is a feature that helps the driver see road signs with the posted speed limit.
RSI's camera has the same limitations as the human eye. See The camera’s limitations for more information about the camera's limitations.
Signs that indirectly indicate the speed limit (such as a sign with a town's name and the permitted speed limit) will not be registered by RSI.
Other factors that may interfere with RSI include:
- Faded signs
- Signs located in a curve
- Twisted or damaged signs
- Signs place high above the road
- Signs that are partially hidden/poorly placed
- Obstructed signs
- Signs that are partially covered by snow, ice, etc.
- Map information that is not up-to-date, inaccurate or does not contain speed limit information[1]
