Nothing in the video says to me that all cyclists should want to ride as shown. Instead, it demonstrates nicely that doing so properly is relatively safe. While some will say "not for me" others will be inspired to venture into traffic they previously feared. Either response is fine.
If speed of slower moving vehicles mattered much, we'd have an epidemic of street sweepers, garbage trucks, and postal vehicles as well as cyclists being hit from behind. For cyclists, being hit from behind is statistically the least common type of collision.
You may fear this kind of accident the most, but though it may be counterintuitive you need to get over this fear to keep yourself safe. "Taking the lane" helps keep you safe from the other,
likely kinds of accidents.
Anyway, great video!
