Come on, these are Germans, do you really they do anything randomly
A bike traveling at 20km/h would be equivalent to an auto traveling at roughly 60km/h.
That makes logical sense to me (honestly).
You are looking at the information the wrong way. The StVZO standard allows for a certain amount of light leakage above the beam cutoff. It's not going to have much to do with reaction time since the main beam is still has the same intensity. Bicycles are held to a tighter standard to avoid "blinding" on-coming traffic which they really can't do given their lane position and lower intensity lighting. Cars can, and do, "blind" other road users. The standard should be tighter for them than for bicycles.
