AVs are not a panacea. Many of the greatest benefits of automated vehicles won’t be achieved until fleet penetration is over 80%. Then vehicles can travel more closely together reducing traffic and, potentially infrastructure costs. In the meantime automated vehicles could reduce costs and increase demand for driving leading to increased traffic, pollution, and sprawl. Other commentators are right to note that there are some bad actors in this space who are willing to sacrifice safety and transparency for marketing and sales. Finally, cities are right to be wary of being used as laboratories and should use what leverage they have to achieve sustainable outcomes that preserve livability and accessibility.
