This article is flat out wrong. Google's autonomous vehicles do the data collection for Google's autonomous vehicles.
They drive ahead of time around every environment in which they want to operate, with a bunch more sensors and more accurate localisation than the streetview vehicles. The lidar on the streetview vehicles is intended to provide a 3D surface model of the buildings lining each street. I find it very doubtful that they'd attempt to do supervised learning of human driving behaviour from the streetview vehicles, rather than the actual automated ones.
