A range of (escalating) possible installations and performances, in the order of feasibility:
1. A police car or ambulance van or fire engine parked in front of the gallery with flashing blue lights running. (permanent installation)
2. If there is enough room available in front of the gallery: a corral (wagon-fort) of 5-6 emergency vehicles with flashing blue lights on.
3. With good relations to the local emergency services and a little roundabout available: One vehicle races around the roundabout with lights flashing and sirens blaring. (If this isn't possible as a live-performance, one could also film it for 5 minutes and present the video in the exhibition as a loop.)
4. If there is more room and there are friends in high places: 5-10 vehicles racing in a circle with lights flashing and sirens at full blast. Live performance.
5. All kinds of emergency vehicles in concentric circles, racing in alternate directions. Clockwise, anti-clockwise, clockwise: Police motorcycles. Ambulances. Fire engines. Police vans. And helicopters above. And drones.
