Isaiah Thomas, known online as hmblzayy, challenged himself to walk more than 3,000 miles, to raise money to build a trade school for children who cannot go to college. He caught the moment live on camera, when a car struck the escort vehicle behind him, which in turn hit him. The content creator said he normally walks facing oncoming traffic with reflectors and a cart in front of him. However, a fan of the stream offered to drive behind him with hazard lights on with an agreement from the police.
