A self-owning car is a hypothetical concept backed by Mike Hearn.
With the emergence of self-driving vehicles, there is the possibility that those vehicles could actually own themselves rather than being owned by corporations. If full autonomy is achieved, and cars able to charge/fuel themselves, receive payments, and be covered by insurance policies, then a car could theoretically take care of itself.
The self-owning car concept is closely linked to self-driving car technology. Without what is known as Level 5 autonomy being available, the technology won't be able to exist.
Some may not be comfortable with the technology, Mike Hearn says the following:
"Some people would find it creepy and weird, and they would refuse to do business with machines," acknowledges Mr Hearn. "They would hate the idea of a machine being an economic equal to them - a modern Ludditism(sic), if you like.
