I honestly think the real toll is the mental concentration required and the stress caused by driving a car. Self-driving cars automatically fix that problem by removing the need for the passenger to concentrate on not killing people. When I take the bus I don't worry so much about my commute time, because I spend the ride relaxing and reading.
