The wildest thing on L.A streets this weekend wasn't traffic … it was the Red Bull Soapbox race that took place in downtown this weekend. The @redbullusa Bull Soapbox Race is a gravity-powered racing event in which teams design and build custom, engine-free vehicles. Participants compete on a downhill course and are judged on creativity, design and speed. The event drew large crowds to downtown Los Angeles as teams showcased elaborate builds, costumes and performances throughout the competition. #redbullsoapboxrace #soapboxderby
