Google said Wednesday at its I/O event that all cars with Google built-in will have YouTube, starting with vehicles from Polestar.

As more new vehicles today feature high-tech infotainment systems promising to add new levels of convenience and entertainment to the lives of drivers and passengers, the YouTube-friendly automobile is expanding in availability. What that often looks like in practical terms is more screens, both up front for the driver and in the back for passengers.

Many cars on the market already have an application-Android Auto -that runs through a connected Android phone and communicates wirelessly with the vehicle to let drivers access their apps on the car's display. However this latest integration is only available for cars that have Google built-in. In other words, it's available for cars that are powered by the Android Automotive operating system; this is a Linux-run open source mobile operating system, modeled after the smartphone. Rather than running smartphones and tablets, Google adapted it so that automakers can use it in their cars, permitting Google apps and services, such as Maps, Assistant and Play, to be directly built into a car.

Similar to other Google-made video and gaming programs, YouTube will only be accessible to passengers and during station stops, the firm says.

The Polestar 2 was the first vehicle to have Google built-in, and earlier this year, the automaker said its Polestar 3 will feature Google's HD mapping solution; the YouTube launch is the next logical step. Google expects to announce more automaker partnerships in the coming weeks and months.

Google has announced partnerships with Volvo and Mercedes. It should be noted that the Mercedes deal is slightly different from this broader offer. Mercedes described it as a licensing agreement that would bring the Google Maps platform, Cloud, and YouTube into future Mercedes-Benz vehicles equipped with the automaker's next-generation operating system called MB.OS.

Google also announced new ways to game in the vehicle at its I/O event. Now, cars with Google built-in will also be able to play games from GameSnacks for Android Auto. GameSnacks is a platform that offers a collection of bite-sized games like Solitaire or Beach Buggy Racing that are fabulous to play while waiting for your car to charge or while picking kids up from school.

Google said at its annual developer conference Wednesday that it expects the number of cars with Google built-in to double by the end of this year. The company did not offer a baseline, but already Google is in vehicles across a range of brands like Chevrolet, Renault, Volvo and Honda, meaning the in-car gaming revolution has even more opportunity to take off.

Others in the auto industry have been pursuing other in-car gaming opportunities. Polestar, along with BYD and Hyundai, is also working with Nvidia to bring the company's on-demand cloud gaming service, GeForce Now, to certain vehicles. Tesla has long offered in-car gaming and last year integrated Steam's library of thousands of games into its vehicles. And last year, BMW partnered with gaming platform AirConsole to bring a collection of single and multiplayer games to new vehicles starting with the 2023 BMW 7 series.
