It is assumed that the Steam support is only being removed for new electric cars. Previously sold cars will retain this feature.
Tesla electric cars gained Steam support at the end of 2022. At that time, it was announced that drivers would be able to play "thousands of games" from the store, including Cyberpunk 2077, Cuphead, and Sonic the Hedgehog.
