Besides what the other user pointed out, there are tens of millions of people driving an hour or more every day just to get to work, and that time sink might feel a bit more bearable if you could relax and do whatever you wanted during that time rather than focus on all the obstacles around you. I don't know that the state of self-driving vehicles will be quite there in my lifetime, but some time in the future they will be, if we keep making progress on them.

You might like driving. For many, driving is stressful.

This is besides the point someone else brought up about how notoriously bad at driving humans can be, and the capacity for how much safer an automated car could be when the tech is matured.

Public transit like efficient railroad infrastructure across the US would be even nicer, but I've about given up on that for the USA. They're doing self driving cars because we sunk too much money in roadway infrastructure (sunk cost fallacy.)
