I'm very much not enjoying chapter 3. Building the highway is trivial and between that and the constant availability of vehicles has greatly reduced the uniqueness of the game. While certain areas are better going walking (like the weather station), it has turned most of the side deliveries in the worst part of any other open world game. There's nothing unique or fun about doing a fetch quests on a vehicle while you don't have to worry about terrain or batteries. Not that the actual systems matter a whole lot, but at least they offer something unique to the table, right now however It's the exact same busy work than the worst parts of any other open world game (GTA, Watch Dogs, AC... take your pick)
I don't think the sense of progression is satisfactory. This type of ease of travelling should have been common only well past the mid point in the game, not in chapter 3. It feels like I'm defeating the point of the game already.
