California Speed has you racing through, of course, California, with a range of different tracks based on the real maps of the state, with short-cuts and branching roads adding choice and variety. Cars include a collection of fast cars, as well as F1 cars and golf-carts, and you can customize your car's paint to suit your style. Split-screen two-player racing is supported.
In the Nintendo 64 version of the game, two of the billboards on the side of the Mojave Desert track display the following message:
God TaKes MOMMIES
aNd PuPPIES AWAY...
According to developer Morgan Godat, he inserted the message as a placeholder after the artists were told on short notice to create new billboard textures for the N64 port. Godat assumed the nature of the text would make it obvious that it was a placeholder, but he later forgot about it and nobody else replaced it. Due to the two particular billboards it appears on being easily missed, the message slipped past QA. It then seemingly went unnoticed by players for several years, as the first online documentation of it was a screenshot posted on Reddit in 2014.
