Wilt, the "voodoo" math you used to somehow calculate that IT WOULD BE OKAY to flash someone in their face in a potentially dangerous situation and then somehow correlate it to a "texting-and-driving" scenario, defies any logic and basic common sense.
All sorts of events prohibit flash photography for just this reason. Watch any NFL game and pay attention to the dozens of photographers surrounding the field and you'll notice that not one uses a flash during the game. The NFL forbids it. It's not becuase the lighting is "good enough." Common sense and basic human courtesy would dictate you don't flash someone under these circumstances.
Could you help me out please? I have another question...Using your logic, could you please figure out for me what the acceptable flash speed would be when a player is wearing black sun-refelctive makeup under his eyes? I'm guessing we could shoot even faster under such conditions.
