Did you know, a couple of years ago, there was already something called BioShift? That was (is?) a controller, NOT made by Shimano, that could be coupled to a Di2 to make it... shift automatically based upon cadence & speed.
But Shift4Me is a whole different thing. You can't compare apples and pears...
