[OSM-talk] oneway yes or true

True, we know nothing with "undefined".

Safety is not engaged in considering a default to yes, but that's what you 
could do on any roads without a oneway. Leading to an unusable, but secure 
software.

True again, this is a driver's requirement.

But I would prefer a software to consider an undocummented value to be the 
default when there is no value rather than making a guess. But your point is 
valid as well in the oneway case.
