Why is a leaking front fork oil seal an urgent safety hazard on a motorcycle?

1. Fork oil leakage causes the rear tire to lose air pressure immediately
2. Fork oil burns cleanly to create smoke signals that distract roadside pedestrians
3. Fork oil loss causes the headlight beam to switch to high beam automatically
4. Leaking fork oil drips down the fork stanchion directly onto the front brake rotor and brake pads, contaminating friction surfaces and causing sudden total loss of front braking power
