Tinker ☀️

@django @linux_gaming - You might look into taking one of the sim citites and intentionally building it car free (example: https://community.simtropolis.com/omnibus/simcity-4/tutorials/how-to-make-a-roadless-city-r89/)

You can use all mass transit forms except for busses (as building for busses would also allow for cars): https://simcity.fandom.com/wiki/Mass_transit

Here is one discussion of someone building similar: https://www.reddit.com/r/simcity4/comments/g0cwic/my_first_serious_attempt_at_making_a_city_with_no/

You would focus on renewable energy: (see multple variants both current to our world and future tech: https://simcity.fandom.com/wiki/List_of_power_plants )

Look into various libraries and community centers and mods etc.
