A method, computer system, and computer program product for using sensor data to modify navigation commands. The method may include predicting a user's navigational action and modifying a navigation command based on comparing the user's predicted navigational action to a recommended navigational action. The modifying the navigation command may include communicating a navigation command to a user based on the user's predicted navigational action deviating from a predetermined navigational action. The modifying the navigation command may include suppressing a queued navigation command to a user based on the user's predicted navigational action conforming to a predetermined navigational action. Predicting the user's navigational action may be based on information received from one or more sensors embedded in a vehicle. The modifying the navigation command may include increasing a frequency of communicating a queued navigation command to a user or decreasing a frequency of communicating a queued navigation command to the user.
