Printing brick roads actually sounds like a pretty interesting step forward even though it isn't the most obvious use of bricks. The drainage is much better than asphalt and that could make a difference in many cities that are dealing with increased flooding. Not so great for snow-plows, though. Before I saw that machine I never would have thought it would be a scalable solution to the problem, though.
