I don't disagree about bikes seemingly getting more complicated. But I'd counter that my 2023 ebike would immediately benefit if all the existing sensors were CAN: from the mid-drive motor+controller, I have the left and right brake sensors running to the front, plus the display, and the headlight power circuit. Branching off the display are the controls for the turning on the bike.

To the rear, I have the derailleur sensor, the speed sensor, and the taillight circuit. I've been meaning to also expose the brake light circuit, so that would be yet another set of wires.

If I had CAN bus today, I'd shrink the wiring down to just: two CAN wires and two power wires to the front, and two CAN wires and two power wires to the rear. All sensors on the front attach to the display. All sensors at the rear are wired as a chain, with the tail/brake lights being at the very end.

The ease of cable routing alone would be worth it. And perhaps those wires could then be armored, for improved resiliency.

It's a little sad that we need to actually say this, but:

Don't be an asshole or you will be permanently banned.

Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.

Focus on discussing the idea, not attacking the person.
