For non-driving scenarios, such as time spent waiting in a parked car or being a passenger, Android for Cars provides ways to bring existing tablet and browser apps to cars with Google built in.
App experiences such as video streaming, gaming, and browsing are well suited to times when drivers are waiting for their cars to charge or for a passenger to show up. And as cars with multiple screens become more common, these experiences can keep passengers occupied as well.
If you have an existing app in another form factor, adapting it for use in cars is a relatively quick process. Currently, guidelines are available for adapting video apps. Guidelines for other types of parked and passenger apps will be similar and are coming soon.
