Was stuck behind a Google delivery van a few days ago.
At first I was confused as what could Google possibly deliver other than #NestThermostats and plushy #Android swag. But it appears that there is a service called Google express that delivers all kinds of stuff to the good little boys and girls of #CambMa .
After all, they see when you are sleeping (android sleep apps), they know when you are home (Nest & Dropcam) they know if you have been bad or good (web searches).
I think there is enough preliminary evidence for an investigation here.
