This is pretty much how I play GTA V. I have a Self Radio playlist for a specific vibe. Hop in a random car and cruise around the city, get distracted by some event, cause a little mayhem and escape if I'm in the mood, and keep cruising. Like the Truck Simulator games, it's a good way to go for a drive without actually needing to go for a drive (so less exhausting, wasteful, and dangerous).
