I always think of these things as tech dreams vs reality. No matter the publicity, no matter the hype, the reality is you will need to change the perception of a global public that have been driving cars for a century. You need to convince the world that it is safe to ride in a car not controlled by a person. I cant see this happening for sometime, decades even. Not only that but driverless cars will disrupt government revenue streams, the workforce, law enforcement etc. every industry will be affected and I don't think people are just going to welcome these changes with open arms. Sure the tech news is gushing with praise, which fuels publicity for these big companies, but in the real world that media will turn on you in an instant when an incident occurs. There will be a large, active, hostile contingent of the public who depend on their jobs driving to feed their families and they wont just sit by and let their jobs become redundant. This isnt Uber, not by a long shot, this is massive global disruption. Like any tech venture, it needs to scale successfully to gain world wide dominance. Prove that it works in a particular environment and expand. Sure companies will love the cost savings that come from driveless tech, but the general public, wow that will be a fight.
