What is the primary hazard when emerging from a highway tunnel or deep mountain rock cut onto an open viaduct bridge during windy weather?

1. Tire pressure drops to zero upon exiting tunnel portals
2. The motorcycle engine will stall instantly from sudden oxygen excess
3. Sudden, unshielded crosswind gusts can violently push the motorcycle across lanes or toward guardrails; riders should anticipate the blast, reduce speed, and apply slight counter-steering into the wind
4. Highway toll cameras will blind the motorcycle's electrical charging coil
