For me, CS1 shows how difficult it is to build effective roads. I solved traffic on my map with an extensive, fast and direct public transit network, and well-connected bike paths along the same alignment for those who don’t want to pay. For roads specifically, timed&sensor traffic lights (TMPE mod) and one way systems in built up areas work well too from what I’ve seen.
I am a little scared of the extra management they’ve popped in to CS2 but I’m hopeful they’ll get the balance right
