Based on our assumptions, a one hour increase in Internet consumption in the United States would increase Google’s revenue by about 9%. Meaning…

2014 revenue from the United States = 28.38 billion.

= 2.58 billion for each hour the average American spends on the internet today.

= $30.93 Billion if there is a one hour increase in Internet usage in the US.

= $32.59 billion in potential US based revenue with 100% self-driving car adoption.

The difference? Up to 4.21 billion dollars per year or more.
