The argument is often made that car travel is essential for economic growth.
However, between 1999 and 2009, traffic in London fell 8.7% while London's economy grew 31.2% and population grew by 10.8%.
From 2009 to 2019 London's economy grew by 36% and population grew by 14%. However, traffic grew by 21%, almost all of it on minor roads.
While Amazon and Uber have certainly played their part, I would argue that it is Google Maps (launched end of 2005) which opened up additional road capacity for drivers and induced additional demand.
