/**
 * BDD E2E Test: Drivers List Page
 * 
 * Tests the main drivers page that displays:
 * - List of all registered drivers
 * - Driver search/filter functionality
 * - Driver sorting options
 * - Pagination or infinite scroll
 * - Driver cards with basic info (name, avatar, rating, rank)
 * 
 * Focus: Final user outcomes - what the driver sees and can verify
