Not trying to be critical, but I never understood why any city would want at grade crossings when they have the ROW for main lanes. I love the FA, and would definitely love to see FA-OWR-1, FAREW, and a connector to/from FA-OWR-1 and FAMIS. In fact, that could be added to Quick change, where it would resemble the NAM MHW-->parallel OWR entrance and exit ramps, RHW style.
Currently there is limited ability to make an exit ramp FA style that will connect to a RHW4 either C1 or F1, inside entrance or exit ramp. Those look kinda cool, and closely resemble a lot of entrance and exit ramps that I have seen, but it is a pain to transition between OWR and RHW-4 all the time, and I am sure it would likewise be painful to do so with OWR-3 and RHW6S, or OWR-4 and RHW8S.
