The Google Product Management department has another young one in the "Google Labs Nursery". It's called "Ride Finder" and it displays cities in the US where there are taxi or shuttle locations for you to get to for rides. There is a link at the bottom labelled: "Information for Fleet Operators" that upon clicking on it reads:
If you'd like to include your vehicles on Ride Finder, please take a moment to fill out this form. We'll get back to you within a week.
I wonder if this is the start of another revenue generating search tool that could see charges to these fleet operators? Or perhaps it will make the Google Adwords keyword space for bus companies and shuttle services more profitable by creating a portal that everyone is visiting.. and clicking on ads. (/end Google conspiracy theory)
The Ride Finder makes use of Google Maps data. Along with Google Local, this is the only other service that I know of that Google is using Google Maps data in.
