Could be a safety enhancement for the Grand tours, reduce the likelihood of M/C camera crews getting in the way…
From a Team’s point of view there could be incentives, agreeing to carry a camera/broadcast package on your team bikes could contribute to the bikes 6.8kg min-weight, and then there’s the question of who owns the broadcast rights from on board cameras?

Helmet cams have been banned from DH race and Qualifying runs for some time, but not practice hence there’s plenty of “riders eye” footage of WC courses being ridden, if you’re into the sport its quite good viewing, but only in short bursts, an hour of helmet cam footage would induce serious motion sickness, so long as it’s used sparingly I can see it adding to the coverage.
