While each lap of 2026 Formula 1 pre-season testing in Bahrain adds to the teams' accumulated knowledge of how the cars will function when the racing begins, questions remain over how key elements of the spectacle will work, and how it will be communicated to fans, spectators and casual TV viewers.
