Traffic Reality Check
- Weekday 6-9 AM / 3-7 PM: Add 45-90 min (LA basin + Camp Pendleton bottleneck)
- Friday afternoon / Sunday return: Add 60-120 min
- Weekend midday: Often smooth — 1:45 achievable
- Border traffic (if continuing to TJ): +30-180 min at San Ysidro
Smart Strategies
- Leave before 6 AM or after 7 PM for best time
- Use Waze/Google Maps live — they reroute around incidents
- Carpool lane (2+) on I-5 saves 15-30 min in congestion
- Metrolink (OC Line) + Amtrak Pacific Surfliner: 2h 15m, $30-50, no parking stress
