Travelers unable to predict or manage EU/EEA immigration queue wait times at border crossings

People crossing into EU/EEA countries at major border stations like Przemyśl face unpredictable, potentially hours-long immigration queues with no visibility into wait times or processing status. Travelers miss connections, experience stress and uncertainty, and current solutions (asking locals, guessing) are unreliable. Real-time queue information and wait time predictions don't exist for most land borders.
