A vehicle is tailgating you. Which response matches ICBC space-management advice?

1. Apply the brakes sharply so the following driver recognizes the danger and immediately increases the gap
2. Maintain a visible, dominant lane position and create more space ahead so you can slow gradually
3. Accelerate well above the posted limit until the tailgater is no longer visible in the mirrors
4. Move beside another vehicle in the same lane so that vehicle creates a physical barrier behind the motorcycle
