The question will be how you can end around the infrastructure and a regulatory framework nearly a 100 years in the a making. The Internet was an entirely new thing that existed outside of the status quo and thus could advance, largely unhindered, as fast as possible. You can imagine the looming regulatory changes this is going to require.
The self-driving car benefits from Moore’s Law, which explains that computers get dramatically cheaper over time, and Metcalfe’s Law, which describes the increasing power of networks as they get bigger and more connected. Both of these laws are now at work on one of the biggest expenses and most powerful forces in our world: transportation.
This is a bigger shift than the smart phone, and it might happen nearly as fast.
