We’ve seen a great number of technological ideas on these pages that help blind people move around the world, but navigation is not enough to travel even moderate distances.

As far as medical uses for autonomous cars, we also imagine thousands of lives saved by having drunk drivers sleep through their driving while the machine steers with a clear mind.
