Why are high-visibility jackets and retroreflective apparel (elementos reflectantes) essential for motorcyclists in Chile?

1. To satisfy aesthetic fashion trends
2. Because motorcycles present a narrow visual profile, and fluorescent/retroreflective gear makes riders visible to other motorists at up to three times greater distance, especially at dawn, dusk, and night
3. To replace the motorcycle's tail lamp
4. To reduce wind resistance by 20%
