I could only manage 5 minutes of the whining and then moved it forward a couple of times. The truth is, unlike the narrator, a person really has to be involved in riding, to endure that video. Non-cyclists would have shut it off after a minute or two.
As far as how people react, I think it all depends on where you live. In communities where there are a lot of active people, and people riding, it is not a big deal. No one I know ever thinks twice about it, or complains. I do consider my self lucky to live in good year round weather and have nearly every road with bikes lanes.
I understand how it would be more hostile is an urban environment or and older community that has no means to expand roadways to accommodate cyclists without doing so at the expense of drivers.
