Most of Taconic Parkway is trunk and trunk_link which never implied
oneway. You should go through in order to improve safety.

Routing is already dangerously broken on some of the ~1400
motorway_link without oneway=* in North America since Mapquest and
Graphhopper don't imply oneway. Without turn restrictions, which I
doubt existing, they might lead you the wrong way.
Example routing: http://preview.tinyurl.com/qxyavwd
Overpass: http://overpass-turbo.eu/s/bu9
I checked a good amount of the North America Overpass query and many
of them, but no majority, implied oneway=no.
