Back on topic, a motorcycle YouTube channel I actually trust posted a rebuttal of the F9 video:
I haven't watched the first one, as I gave up on F9 ages ago as well-produced but sensationalist garbage. The YouTube need to come to some grand proclamation, followed by a pat conclusion, runs strong in them. And they're nowhere near as smart as they think they are, trying to apply their Grade 12 physics to PhD level problems.
Despite (or perhaps because of) their funding by an insurance company, the Bennett's videos are far superior to F9. The one they did before on riding jeans, tackling some of the more outlandish proclamations by the idiots at Motolegends (mostly that you should buy $600 pairs of jeans from them) was also excellent.
