What is the primary rule for safe motorcycle riding according to CONASET's Libro del Nuevo Conductor?

1. Assume all other drivers see you and will always yield right-of-way
2. Practice defensive riding: ride as if you are invisible to other drivers, anticipate potential mistakes of others, manage space cushions constantly, and wear complete certified protective gear on every ride
3. Rely entirely on your loud exhaust to clear traffic
4. Drive at the absolute maximum speed the motorcycle can achieve
