/**
 * BDD E2E Test: Driver Rankings Page
 * 
 * Tests the detailed driver rankings page that displays:
 * - Comprehensive list of all registered drivers
 * - Driver search and filtering functionality
 * - Driver sorting options (by rating, name, rank, etc.)
 * - Pagination or infinite scroll for large driver lists
 * - Driver cards with detailed information
 * - Driver profile navigation
 * 
 * Focus: Final user outcomes - what the driver sees and can verify
