Dash cam captures empty vehicle driving on its own

When driving around the Jonquière streets, this person came up to a stop with a strangely behaving pick up truck. The truck very slowly crossed the 4 stop intersection, which was odd at first, up until she noticed that there was absolutely nobody inside. Slightly panicked, she quickly drove in front of it further and she tried to stop it by getting in front and pushing it without success. The truck eventually hit an electric pole which stopped its course. As it turns out, the pick-up truck had been forgotten on drive while its inattentive owner disappeared who knows where!
