The weirdest part about not being able to mount in Solution 9 is that the city is clearly designed to be drivable. There are literally cars, and trucks, parking garages, and motorcycle dealerships, and whatnot. At the very least we should be able to use the new motorcycle mount THAT THEY LITERALLY SELL THERE IN THE CITY! (just make the area near the crafting NPCs a "hoofing it" zone", and call it a day.)
