Those are pretty recent designs, but I like them for the most part. I agree, as long as you are not hampering human movement, keep car traffic slow and safe for said human movement, networking with bike paths is fine in my book. In an existing dendritic US-style street system, retrofitting with bike paths between streets is a really cheap and easy way to encourage biking (the hardest part is probably dealing with existing property rights)
