Where should the driver direct evacuated passengers to gather after exiting a bus that has broken down or caught fire on an Austrian motorway (Autobahn)?

1. Gathering on the left passing lane to flag down oncoming cars
2. Behind the roadside safety guardrail (Leitschiene), well off the embankment/hard shoulder, and at least 50-100 meters away from the vehicle upstream of smoke and wind
3. Sitting on top of their luggage inside the bus entrance steps
4. Dispersing in all directions across active highway lanes
