A Chapel Hill transportation advocate has asked the town to make it illegal for drivers to open their car doors without making sure it is safe to do so. Tab Combs, former chair of Chapel Hill’s Bicycle and Pedestrian Advisory Board, submitted a petition Jan. 31 asking the town to adopt a local anti-dooring ordinance. The Chapel Hill Town Council will hear the petition and get a bike and pedestrian safety update Wednesday night, just five days after a cyclist died from injuries he suffered in a Jan. 25 crash on West Franklin Street.
