There is one big difference between both Cancellara incidents and the one confirmed case of motor-doping that we have seen (Femke). The latter created a gap and rode away from the best riders in the world on the Koppenberg - where everyone is at their maximum going 100%.
Cancellara in PR rode away from the bunch when no one really wanted to go to the front and when there was a bit of looking around.. There was certainly not a concerted effort to chase him and its conceivable that he could have been putting out 200 watts more than the rest to create the gap - without needing a motor. In RVV he rode away from only one rider on a brutal climb towards the end of a really tough race - again its possible that he was just able to put out 200 watts more at that stage in the race - perhaps Boonen was just cooked.
That's not to say that Cancellara didn't necessarily have a motor - but just that the way the gap grows is not really a smoking gun, because it's dependent on two factors. The power of Cancellara, and also the power that the other riders are putting out at that moment. In Femke's case, it was much more clear cut, because she easily rode away from several of the best riders in the world at a place on the course where everyone would be going 100%.
this has been said plenty of times, but i'll spell it out again if necessary:
It's not about his speed, or about how quickly the gap grows, or about who he leaves behind.
It's about the unreal combination of
1. accelleration
2. cadence
3. gear choice
4. his position on the bike
4a. in-saddle
4b. (lack of) upper body movement (arms are hardly pulling the wheel, shoulders not moving, etc.)
Any given, traditionally doped rider X may go up the Muur quicker than Cancellara did, but said rider will never. ever. do so in that particular style following those 4 criteria. Unless he's using a motor.
