A tiny Chihuahua wreaked havoc on a major freeway in New York after escaping and running down the four-lane carriageway.Video captured the moment drivers frantically tried to capture the dog, named Bean, after spotting him running down the Staten Island Expressway late last Tuesday.The now-viral dashcam footage shows cars slowing down to a crawl with their hazard warning lights flashing, before one driver pulled over and gave chase on foot.“When I saw that dog, my instincts just kicked in, and the only thing on my mind was to make sure that dog got to safety,” driver Katie Marie, whose dashcam captured the rescue mission, told the Staten Island Advance.“We just kept trying to keep the dog in the [high-occupancy vehicle] lane, trying to tire him out.
