The first impact of self-driving cars will be much worse traffic. While ride-sharing and public transit are helpful, they are nowhere near as good as self-driving cars.

If you had a self-driving car you'd be able to set up a truly productive or relaxing environment, which you're unable to fully replicate on public transit. For example, stick in a mattress with your favorite pillow, add a shower, have a desk with nice big monitors, a webcam to take video calls, etc. Aside from just being transportation, a car is also a bubble of quiet, cleanliness, and personal security. It is a mini house on wheels, a portable locker, and a refuge.

And since you're not driving, who cares about the traffic?

Eh I can't find citations right now because I am trying to be productive but modellers and people who study this argue that a lot of traffic is caused by sub-optimal driver behavior. Specifically issues with merging/ and phantom waves that build up and cause phantom jams. Accordingly people think the self driving cars will not be susceptible to this -> less traffic(?). I do not know I agree with these claims since I haven't looked at the math but I am not so sure self driving cars will lead to "much worse" traffic than human driven cars.
