Thieves in Fremont, California took two PlusAI trailers because they had Nvidia logos on them. They got about half a mile, then opened the doors. Each trailer held 20,000 pounds of sand, 40,000 pounds in all. PlusAI packs the trailers that way so its Nvidia-backed autonomous trucks can practice hauling freight. The computers were in the cabs, which stayed in the warehouse. Police recovered both trailers with the sand still in them. No arrests.
