PHYSIX OBSERVATION

Moving emergency float from off-roaders down to an executive flagship shows BYD is treating extreme safety as a new selling point for ultra-luxury. For users, automatic activation on water entry lowers the operating threshold in a panic; for the industry, ultra-luxury competition is shifting from spec-stacking to scenario-based safety, but the real-world effectiveness of the float capability still needs to be verified against actual accident data.
