I’m thinking about the use case for normies who don’t picture anything when you say “bike computer”. There’d need to be solid ecosystem support - the device would need to be vibration hardened (I’m sure they could make $$$$ on that alone), there would need to be great mounting and charging options, a bike version of collision detection, bike-optimized turn-by-turn, and probably integration with bike telematics+rear collision systems, when that inevitably becomes a thing. It should probably double as a dash cam using the cool wide angle stuff they’ve shown with continuity camera.

Wouldn’t it be great if your phone could call 911 automatically when the guy rolling coal on you decides to just run you down?

See that would be an interesting feature to add. They have sensor-shift image stabilization and some sort of focusing, perhaps they could add a feature to lock all of that so it couldn’t be damaged by vibration while riding a bike.

Why not just get a cheap $20 dollar android? That's what I usually see food delivery drivers use.
