Uber's experiments are potentially just the beginning of what will become the new normal in transportation. Rajkumar and other CMU experts note partial autonomy is already here. Within two to three years, self-driving vehicles in controlled environments such as shipyards and airports could become the norm. Full automation for personal vehicles, Rajkumar predicted, is about a decade away. Lee, who said development will accelerate as private companies like Uber invest more in the technology, thinks 10 years may be a conservative estimate.
