Alphabet halts sales of Laser Bear Honeycomb lidar sensors. The head of the division just left Waymo for Aeva, and I would guess this is a prelude to winding down the lidar effort. There are enough lidar start-up in the ecosystem now that it seems unlikely even Waymo could outperform all of them as a side project.
Nuro builds a test track at Las Vegas Motor Speedway. Back when I was at Udacity, we did driver safety training at Sonoma Raceway. Those track has a lot of space and are only fully utilized a few days a year. Makes sense that a permanent tenant could be valuable.
