In the near future, will we see a widespread commercial use of autonomous vehicles?

Last week, Google released a video that demonstrated the potential of its self-driving car. The video showed a legally blind man, who after taking the driver seat of one of Google's robotic cars, maneuvered from his home, through neighborhoods, and into a commercial center (including a local Taco Bell!). The car, which features radar, lasers, and cameras, allowed the man to take a ride without touching the steering wheel or pedals.
