It's a solution to a problem, but said problem is not the root cause. Reduce the need for driving in the first place; normalize public transit within city limits, improve city designs by putting shops and work closer by, redesign cities to be more pedestrian and cyclist-friendly (and I'm aware cyclists get plenty of accidents too, I live in a cyclist country), etc. These are not easy things to fix, because especially in the US where I believe this is about, cities aren't designed like this in the first place and can't be redone easily.

First, if drivers make mistake, make them more accountable; require better training, enforce laws more strictly, etc. What are the causes behind traffic accidents? I'm confident the majority is from reckless driving, disregarding other drivers, speeding, impatience, alcohol / drugs, etc. Another percentage will be from unsafe driving conditions, which self-driving cars won't fix because they'll refuse to work in those conditions.
