Techniques are described for monitoring whether a user is following directions to a destination during electronic navigation to the destination provided by an electronic navigation device. When the electronic navigation device determines that the user is not following directions to the destination (e.g., the user has missed several turns suggested by the electronic navigation device), the electronic navigation device determines that the user appears to be avoiding the route (or a primary component thereof) to the destination. In response to a determination that the user appears to be avoiding the route (or a primary component thereof) to the destination, the electronic navigation device may automatically, without human intervention, perform an operation directed to using an alternative route (or alternative primary component) to the destination despite the current route remaining preferred according to current routing settings.
