More public transit and more public spaces. Transit that you don’t have to think about taking (because it’s safe, frequent, and cheap or free) takes you to new places or to familiar places more often, and lets you meet more people more often. And going outside and doing shit is just good for you, I’m sorry to report.
Public transit isn’t for socializing, it’s for traveling. Public spaces like parks, libraries, squares, etc that don’t require payment to use are for socializing.
