Similarly, turn on assist at just the right time and maybe I can gap you off the back into a headwind at little cost to myself. I wouldn't personally do it, but I can see how someone might think that a stealth motor used very judiciously would give them that last little edge that they "need".
I just don't see it happening. All of the 'stealth' bikes top out at 28mph which won't help on a slight downhill, tailwind or sprint. I think they're great for commuting but don't think they belong in group rides. I have a Copenhagen wheel I occasionally use for commuting and don't think it would be very save riding in close proximity to others.
