They can legally blind cyclists but not the other way around. (

When one considers the m/s, a 3.083-fold increase in Lux at the same distance results in the same reaction time for distance to fixed point.
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).
