FWIW, the laser diodes face backwards and are not in the visible range. They excite a phosphor in the back that converts that energy to the visible range, and that light is directed by a reflector. IOW, they do NOT face forward, or are in the visible range, so their spread could be anything that the engineers wanted.
In the USA, the FDA (not DOT) forced BMW to add a safety switch to shut the lasers off if the housing was broken before they would approve their use in the USA (the DOT controls lights, but the FDA controls lasers, so it took awhile to get both of them happy to approve their use in the USA). They were worried that without that, the invisible light from the lasers could possibly end up pointing forward and blind someone. Whether that is anywhere near a likely situation, can't say, but that's why they forced that redesign. No idea how well it works.
