I've never had that happen. Part of the problem in his video is a reluctance for the motorist to cross the dotted line. Once a motorist realizes that they are forced to cross the line they typically wait for a clearing and give a much wider distance.

Those lanes looked about 10 feet me. Its impossible for me to tell of course but anything less than 13-14 feet is to narrow to share with an auto. According to AASHTO is actually 14 but personally I've found 13 acceptable to me.
