It seems all the hCaptcha verifications I receive are for buses, boats and trains? They don't seem limited by geography or by recency. I'm curious why these particular artifacts and whether this has always been the case.

#8First, I’m going to teach you to fish. Go to hCaptcha’s website, then scroll to the footer. Click around on the about links. It’ll reveal their business model. This trick also works for other businesses and NGOs.
