There was an old, now defunct, satire magazine called "CARtoons" that once did a piece on Earth's entire civilization being confined inside of large self-driving cars all barreling down the highway and going nowhere in particular. Everything was self-driving, the mall, restaurants, offices. It's hard to find any scans of the magazine online, but archive.org has a few (not that issue in particular) if you want to get a feel for them.
