The California Department of Transportation (Caltrans) is testing an interesting machine to move the lanes in the commuting highways and although it works slowly (just 5 mph.) the extra channel is highly appreciated by the users who find an extra lane whether they go to the downtown or are trying to back home.

Common people calls it a “zipper”, take a look in this video and you’ll understand why.
