What will the future of cars be like? Video games may have the answer.

In-car gaming itself also seems poised to have a moment soon, especially as occupants need entertainment while charging their electric vehicles. Cadillac demonstrated exactly that at CES, partnering with Microsoft to make an in-car racing game in a Lyriq EV, played using the wheel and pedals of the car. Tesla beat Cadillac to the punch with more than just a demo: In December, the electric automaker rolled out Steam gaming to the Model S and Model X, allowing occupants to play thousands of titles on the central screen while parked using a Bluetooth controller.
