Waymo, the self-driving spinoff of Alphabet, is the latest firm to offer up some of the information gleaned from its vehicles to the wider research community.

The news: Waymo says it will share some of the data it’s gathered from its vehicles for free so other researchers working on autonomous driving can use it. Waymo isn’t the first to do this: Lyft, Argo AI, and other firms have already open-sourced some data sets. But Waymo’s move is notable because its vehicles have covered millions of miles on roads already.
