Are All Those Farkles Really Necessary?

Do you mean that they are more likely to aim at my lights?

With regard to car lights my X3 has adaptive headlights which, when activated, totally manage my forward facing light output, not just for oncoming traffic but also vehicles that you are following. The advent of LED lights with their brilliance can be a real problem so I'm surprised that the powers to be haven't legislated on light management systems being made mandatory.
