The second order consequences of autonomous vehicles will be even more significant:

1. People wont need to own cars any more, which is saved capital
2. People won't need garages. Saved space and construction costs
3. No space will be needed to be reserved for parking close to buildings. This will change how the world looks but also reduce exercise
4. The road network will be used more evenly and efficiently
5. It will be cheaper to "drive" outside of peak time, so traffic spikes will decrease
6. Better safety will lead to lighter vehicles, reducing manufacturing costs and road wear
7. Less buses. Why would anyone tie their schedules to inflexible public transport
8. No need for drivers license. Money saved
9. They can pick up post and parcels, so it will make package delivery cheaper
