Fortunately, or unfortunately, we will not see any driverless cars in the near future.

Currently, the state of the art in driverless cars, IGNORES bikes because the computer can't compute their path. So, basically, the programs are blind to bikes. Further, the programs fail when they process that the bum is a piece of road furniture (non-moving) and then it moves, causing a execution fault. And, that is the state of the art, of what is. A LONG WAY from being reliable.

But, what is going to kill the driverless cars is the future.
In the near future, people will be leaving cities to live in rural communities.
As the financial crisis hits, while more people are being more aware of what they eat, the exodus will be happening.

And, driverless cars, a solution for the problem of urban congestions will find itself a solution of a problem that no longer exists.
