Google has announced their autonomous driving prototypes have progressed far enough that the company will begin testing a handful of them on the roads outside their headquarters in Mountain View, California.

The prototypes will be limited to speeds of 25 mph (40.2 km/h) and each model will be equipped with a removable steering wheel, accelerator and brake pedal so a "safety driver" can intervene if necessary. 

However, Google thinks this is unlikely as the prototypes will use the same software as their existing fleet of self-driving Lexus RX450h crossovers which have already logged nearly a million autonomous miles on public roads since the project started.  The company went on to say their autonomous driving fleet has already logged the equivalent of about 75 years of typical American adult driving experience.
