"A level 4 autonomous vehicle will be for sale in the US to ordinary customers (80 percent)"
When this becomes universally adopted, it's going to have a bigger impact than anyone thinks.
Cities now derive revenue from traffic fines, parking fines, parking fees, and so on.
Level 4 autonomous vehicles are going to obviate ALL of that which means cities are going to lose more and more revenue as they become adopted.
And nobody is thinking about how to replace that revenue.
