Certainly looks too close to me.
One word of warning though....it can look closer than it really was if they pull in sharpish after you. This is because of the camera's reduced field of view, i.e. it sees ahead of you and not besides you. In this clip he does look like he is pulling in quickly, thus giving the impression of being closer.
However, despite that, it still looks like he was well within 3 feet when next to you.
