Whenever I channeled my traffic through my own VPN (Digital Ocean), I would get the "Are you a robot?" screen very often (at least hourly).
I suspect that this is intentional and a way to punish people who are trying to avoid tracking cookies.
1) You are all on a VPN that's hosted at AWS or another cloud provider. Google assumes you to be a bot based on the IP address being in a data center.
2) Someone is doing a lot of scraping through a computer in the office, which triggered Google to flag your office IP address for bots (which in this case would technically be correct)
If not try with a turing test.
Also: It's utterly frustrating to pick cars, front-end stores, bridges etc. The process is also slow as hell. Worst UX ever for a problem that's really not mine but actually theirs.
