Did this truck driver deliberately hit a car?

A truck caused a fender-bender accident on the Ken-? Expressway near Hachi?ji Nishi IC in Tokyo. The scene, filmed by a dashcam, shows the HGV abruptly changing lanes before continuing on its way without stopping. The motorist filming the scene decided to follow. After about 25 kilometers, he managed to stop the truck at the Sayama PA service area and immediately notified the police. The video is circulating online, but beware, the background music is quite loud.
