Google's not a phone company either, but they sell phones. Why would you not expect them to sell cars when they're obviously dumping so much money into auto technology?
Because that auto technology is not meant for users. It's meant for them to get a more accurate and up-to-date street view for Maps. Android is an extremely user-facing technology, and furthers their efforts to control as much of the mobile ecosystem as possible.
