Helmet cam's image quality wasn't limited by bandwidth as it was using same broadcast method as all other onboard cameras, it's probably best it can do in such small form factor.
I highly doubt that. Even mobile phone cameras can do better, with actual image stabilization.
Some thoughts from my experience building real-time camera/imaging systems (neither refuting nor supporting the points above).
The video I posted above about the 2018 season is probably built with 2017 era cameras. That might sound old but most sensor manufacturers do a yearly or 18 month refresh of sensors in the HD to 2k range. The throw cameras on at the high end of the range but even now that is slowing down because multiple-sensors+lenses is the new consumer battleground. The sensor is probably good enough.
Most of what we are seeing in mobile phone image improvements in the last 3 years are AI driven. Maybe 1/3 of the AI bling in the last years are enabled by the pretense of multiple lenses or sensors - simultaneous imaging lets one do super-resolution, focus blending, blurring, (better) HDR, etc etc.
None of that is feasible however to do in real-time at the moment.
There would be some value in a partnership with Huawei or some mobile imaging / camera partner as 2022 era camera SOCs could run in real-time some AI upsampling/cleaning in on 2017 era camera resolution cameras. They could engineer something themselves. But quite a lot would need to be on-device which would end up being itself a compromise that would be interesting to design.
There are also optical and form-factor constraints in the roll-hoop enclosure that are going to be different to phones. For example, the motion will necessitate larger pixel sensors (of which their are fewer) in order to keep short exposure times to have some control over motion blur. This affects compatible lenses and what lenses are available. Meanwhile on the mobile phone they just fake this in software - possible 'generally' only because they are not doing it in realtime.
People should not underestimate how many hundreds of thousands (millions?) of man hours of engineering have gone into mobile phone imaging tech.
