And as I told you, the latest findings about children's ability to judge the speed of a vehicle supports those recommendations.
Ah, I found it:

Hagen asserts that Danish evidence demonstrates that some age groups have a high car-bike collision rate because they don't know how to obey the rules of the road for drivers of vehicles. How do the Danes develop such information, since the predominant cycling mode is not vehicular cycling? Pardon my skepticism about what the Danes say about the ability to perform vehicular cycling.
The Danish claims about the inability of children to estimate the speed and distance of vehicles for traffic purposes are not made, according to the abstract, from actual measurement of this ability, but are calculated from some measure of visual acuity. Again, pardon my skepticism about such claims.
