This is not how to car pool.

Residents of a home in Hinchinbrook in Sydney's south-west received a mighty shock when a Mitsubishi Lancer smashed through their fence and into their backyard pool in the pre-dawn hours of Friday morning.

Three young men who were in the car climbed out of the vehicle and were not injured, Inspector Phil Brooks, from the Traffic and Highway Patrol Command, said.

Inspector Brooks said the men told police they were driving in Hinchinbrook about 4.30am when a taxi crashed into their vehicle. The crash sent their vehicle into a spin, before it careered through the fence and into the pool.
