How to make walking NPCS like GTA

Hello, im currently working on a GTA type story game and I want to have randomly spawning NPCS, would anyone know how to make random movements that look realistic?

Thanks

Personal opinion only, lol. Completely random doesn't look very realistic. It looks more realistic when it looks like they have a goal.

I'd probably create a list of predefined paths and randomly pick from those.

Like, from housedoor to shop, to park, back, etc.

Just an idea
