1. I-405 car crash, Los Angeles, US:
- In February 2015, a major pileup occurred on Interstate 405 near Sepulveda Pass in Los Angeles, California.
- It involved approximately 75 to 100 vehicles, some of which caught fire following collisions.
- This incident resulted in over 60 injured people, some with critical injuries, but fortunately no fatalities were reported.
2. M5 Ringway Pileup, Germany:
- In September 2017, a massive multi-car accident occurred on the A3 Autobahn, also known as the M5 Ringway, near Frankfurt, Germany.
- It involved dozens of cars, trucks, and other vehicles, with more than 150 estimated to be involved.
- Tragically, this incident resulted in numerous injuries, including several critical ones, and sadly multiple fatalities were also confirmed.
These are two major accidents with a high number of vehicles involved, but I must emphasize that it's difficult to pinpoint one definitive instance as the "biggest car crash worldwide." Various accidents around the world may have occurred involving substantial car counts with varying impact and consequences. Authorities and relevant sources would maintain records of notable incidents in their respective regions.
