Google recently announced that its fleet of driverless cars hit 300,000 miles. Accident free. That's an impressive feat for driverless cars, but what isn't clear is how many miles were spent on private roads or desolate test tracks.

Google says that while the cars have come a long way, they still have a long way to go... or drive. The vehicles still need to overcome snow and ice conditions, as well as construction zones, and if the cars drive in Chicago, the massive array of potholes.

What will be interesting is to see how quickly these vehicles become involved in accidents, now that Google has disclosed that they will be hitting the roads, used as commuting vehicles by Google's team. I think it'll be pretty easy if these cars are so successful for a police officer to determine who's at fault. I'll guess that the human driver will be cited over the drive equivalent of Deep Blue.

Are you ready to see driverless cars on your local roadway? If you answered no, you don't have to worry, it won't be anytime soon. Nevada is the state where all this testing is ongoing, and I'm sure the vehicles are nowhere near ready to take on the Vegas Strip. And when it is, we'll see how far it can make it.
