No - the correct list is legal-talk, so please follow up the conversation

Short answer: yes.


Long answer: The majority of license-aware OSM users do believe that, as long 
as you keep the information layers separate, the attribution of both layers 
separate, and a normal user can tell apart which is which, putting several 
layers together is not considered a derivative work but a collaborative work, 
and the CC-by-sa license does not have to be enforced to turn the other 
layers into CC-bt-sa -covered material.

Even if the CC-by-sa license would ever "contaminate" your traffic and routing 
data, the license does not have the "nc" component, so you'd be able to 
charge money (though in the worst case, you'd have to release traffic data 
under CC-by-sa after you're charged for it).
