Maybe not carpooling, but proponents of self-driving cars often talk about how their efficiency (i.e. algorithmic efficiency in how they drive) would greatly ease traffic congestion. Much of the issue with traffic is just bad drivers (inefficient merging, accidents causing backups to name a few examples) but also current traffic controls like stop lights could essentially be removed if cars could reliably communicate with each other.
