Why do painted road markings (e.g., pedestrian zebra crossings, lane dividing lines, and turn arrows) present a major hazard to motorcyclists in the rain?

1. Road paint emits magnetic waves that disrupt the motorcycle's ABS wheel speed sensors
2. Painted lines soften in rain and adhere like glue to motorcycle tires, stopping the wheels from turning
3. Thermoplastic road paints lack porosity, creating a micro-layer of standing water that dramatically reduces tire friction compared to rough asphalt
4. Reflective paint causes motorcycle tires to expand and over-pressurize
