San Mateo County, California - Two adults and two children have survived after they accidentally drove off a harrowing cliff in their Tesla.

Video shared on Facebook by the Golden Gate Division Air Operations shows the mangled remains of the electric car as it lay wrecked among rocks near the shoreline.

The car was reportedly heading southbound on Pacific Coast Highway in California on Monday morning when it drove off the cliff, known to locals as "Devil's Slide," flipping several times before landing on its wheels 250 feet below.

Other drivers witnessed the accident and immediately called 911.

A rescue unit propelled down the cliff, finding two children, aged four and nine, and two adults having survived the crash.

According to Fire Chief Brian Pottenger of the Cal Fire San Mateo-Santa Cruz Unit, "everyone was shocked" when responders spotted movement through the windshield of the car, describing it as an "absolute miracle."

He also commented that while the children suffered some minor musculoskeletal injuries, they were both in car seats that he believes "saved their lives."

The adults suffered moderate traumatic injuries to multiple parts of their bodies.

The California Highway Patrol is unsure of what caused the accident, but noted that the car was not believed to be in self-driving mode. They are currently conducting an investigation into the incident.

The four victims of the crash are currently being hospitalized at Stanford Medical Center, but are expected to make full recoveries.
