On a long climb, timed right as part of an attack, it would definitely, definitely be a help. The difference between the top riders is so slim that it would without question make a difference, in my mind.

I think the Cancellara video looks odd, but he is super-human...

The Hesjedal video is just super weird. He could have knocked the motor on during the fall. He also gets up in a really suspicious manner IMO...

In the Cancellara video, the riders around and in-front ease up a bit just as he accelerates. It does look odd, but he's a freak of nature when it comes to long, solo efforts. And, he rarely looks "out of sorts" on the bike. The only time I recall seeing him look completely gassed was after winning Paris-Roubaix a few years ago. And that was after he won and collapsed in the in-field.

Exactly.

In the first clip you posted, at the end in the tour of flanders when Cancellara attacks before the finish, neither his cadence nor his body position change as he accelerates. Further, the rider behind him who is undoubtedly an incredible athlete has to stand up just to keep his current pace.

At the very least it's not hard to see why this looks suspicious.

By the way, have you seen this? I think it just came out a week or two ago.. https://www.youtube.com/watch?v=Wv5F5N6mFf0
