John Salangsang/AP Authorities are discouraging social media users from filming themselves exiting moving vehicles for the #InMyFeelings challenge. The challenge was inspired by the social media comedian Shiggy, who posted a video of himself on Instagram dancing to the Drake song "In My Feelings" on a residential street. Since Shiggy posted his video in June, others have filmed themselves getting out of moving vehicles and dancing alongside them or falling while attempting to dance.
