If I stop in the wrong gear the most dangerous part is that I stopped, not that I'm in the wrong gear. If I'm moving the bike by directly motivating the drivetrain with my foot, all this talk about "more control" feels very silly because I am already directly exposed to whatever is happening on the chain and at the wheels. I don't ride an ebike but because my tires are skinny I can definitely slip out if I start too fast in a low gear. The "fix" for that isn't to pick a different gear or rely on some fancy shifter to try and increase my mechanical advantage, it's to feel the tires slipping at my feet and just... pedal slower. Ditto for going up hills. Is "the bike got hard to pedal" cognitive load or literal load? I get the argument for riding a cargo bike but IME cargo bikes are almost always ebikes now because derailleur or not, not many people are going to accelerate quickly with kids and dog. Considering that fancy non-deraileur gearboxes cost nearly as much as cheap ebike conversion kits it seems like an uphill battle.
