You can go through the starting options with the up and down arrow keys and select things with the enter key. If you go in the options you'll see a CONTROLS section. Press enter on that and you'll be able to see all the keyboard keybindings and if you wanna change them you can go down to the AUTO CONFIG section and press enter which will allow you to change them but basically the keybindings are:
Gas: Z Brake: X Look Back: C Drift: Space
(To move around with the car you use the left and right arrow keys)
