Any good Cities Skylines-style game with support for bike lanes, bus lanes, bike paths and pedestrian paths?
I think it'd be cool to design a virtual city with easy bike/pedestrian access to nearby shops, schools and other amenities while minimizing car dependency (as therefore the pollution, noise, parking issues and noise that come with it).
You can get very close with C:S mods, for example road builder will let you design roads with pretty much any lane configuration you want including bike and pedestrian areas. I'm a very anti-car person and I love C:S because it lets me build a city the way I wish my hometown was. You just have to tweak the game a bit to get away from the car-centric starting progression.
I don't have a complete list right now unfortunately, but here are some off the top of my head, all on the steam workshop:
Traffic Manager President Edition: set speed limits, restrict vehicle access and manage traffic priority
Road Builder: create your own road assets from scratch with highly configurable car & bike lane layouts
Transfer Manager: control the flow and active area of service and delivery vehicles
Intersection Marking Tool: allows you to paint intersections to get continuous bike paths, shark teeth indicating yielding, etc
Also, I highly recommend the Plazas & Promenades DLC. It adds native support for pedestrian-only areas that only need service points at their outer border for deliveries and services. I've had quite a lot of success just making large parts of the city pedestrian zones and guiding delivery vehicles through a few central arteries with service points. If you combine this with the mods from above you can get a city with a modal split rivaling the Dutch.
Also something pretty much mandatory imo: network extensions 2. This mod adds a ton of new roads including some pedestrian zonable streets. Also highly recommended: realistic population. With this mod the tallest buildings will have space of up to 100 households or so which makes it easier to build cities without car dependency.
And finally, something that always bothered me a bit is that in the beginning of the game, all new cims arrive by car, which makes my city car-dependant from the beginning. Well the island of Saint Martin has absolutely zero infrastructure, so you can have all your cims arriving by ferry or plane. Note that the airport and dock isn't unlocked until much later in the game, meaning you need to play with the "all milestones unlocked" mod in this map.
