I would like for you to include weather alerts from the National Weather Service as an automatic alert when we are driving toward an area with a weather warning and when an alert is issued for the area we are in. For example, if I am a few miles away from a tornado warning I would like to know about it before I get to that area so I could find a safe place until the warning is passed. We shouldn't need to depend on user-reported weather alerts; we also need the warnings from the National Weather Service.
In addition, a map overlay showing weather warnings would be very helpful. I would also like to be able to see a weather radar overlay on the map. I have read that Apple currently does not allow weather radar in CarPlay; however, perhaps you could convince them to allow at least a static radar overlay so we can be aware if we are traveling toward areas of bad weather.
