I think I have it now, we just need to tweak traction to make sticking to roads a meaningful option, and/or have them set up chokepoints that matter, like in roads through forests or bridges. Either way it buffs (or avoids nerfing) walking because you can just go around.
I like the toll road concept too, it’s clearly something that survivors are going to do.
Nope, you can drive a bicycle or a low-powered car or whatever through the worst terrain around and it’ll be fine.
That part of it is really compelling, they’ll be able to see/hear most vehicles from a long way off, and set up an ambush or something, whereas a player on foot is just not going to be noticed.
In general I agree, we want some kinds of threats that remain stationalry so you only deal with them if/when you go looking for trouble, but other kinds of threats that come find you no mater what you do. Ideally you’d even have threats thatif you DID encounter them in a vehicle, the best option would be to retreat to a base and deal wit them defensively.
Feel free to have this discussion, but in another thread
