From description on YouTube: Shot on the actual streets of San Francisco, California, GYM5 features a focus on fast, raw and precise driving action. Filmed over four days, director Ben Conrad and his team are back to work on their second Gymkhana production and delivered the entire city of San Francisco as Ken Block's personal gymkhana playground.
