Google Ventures operates independently from Google, that is, and it makes entirely financially-driven decisions with how it invests its money. This week Google Maps was updated to include an Uber link in its suggestions for how you might take public transport from one place to the other.
Uber is a company that will send a car to your location, pick you up, and drop you off wherever you like for a fee. This company is a "vehicles for hire" organization which had a major investment round that included Google Ventures in September of 2013.

Google isn’t necessarily going to move ahead at this point and acquire Uber - but you never know. Google Ventures was an investor with Nest Labs back in 2011, after all.
