1. A method comprising:

  • detecting, at an application executing in a device in a vehicle, in a conversation occurring between two users, a phrase;

    determining that the phrase is usable in providing a navigation directive;

    performing, using Natural Language Processing (NLP), a deep parsing of the conversation, the deep parsing extracting a context applicable to the phrase;

    evaluating the context to determine whether a likelihood that the context is related to a navigation instruction spoken between the two users during the conversation for navigation of the vehicle is greater than a threshold;

    computing, at the device, from the conversation, a future location of the vehicle during the navigation based upon the navigation instruction responsive to determining that a likelihood that the context is related to a navigation instruction spoken between the two users during the conversation for navigation of the vehicle is greater than the threshold;

    identifying, using data from a data source, a suboptimal driving condition on a route between a present location of the vehicle and the future location; and

    alerting a user in the vehicle about the suboptimal driving condition on the route.
