Why are standard everyday cotton denim jeans inadequate as protective apparel for high-speed motorcycle riding compared to certified riding pants?

1. Denim jeans create magnetic interference with the motorcycle's digital electronic control unit (ECU)
2. Standard cotton denim shreds in less than one second of asphalt sliding (0.5–0.7 seconds), providing negligible abrasion resistance against severe road rash
3. Standard cotton fabrics increase air drag to the point of causing high-speed front wheel wobble
4. Denim jeans are strictly classified as hazardous flammable materials under PRC transport regulations
