How to Drive Your Go-Kart Indoors and Underground

Mounting and Basic Controls

Walk up to a placed mechanical go-kart and press your use key (right-click by default) to climb into the driver's seat. Once seated inside the 3D vehicle, use your standard movement keys to accelerate, reverse, and steer across the ground on wheels. You can also toggle third-person view with F5 to get a wider look at your kart's clearance around tight corners. When your trip is finished, press your sneak key (Shift by default) to step out beside the kart.

Clearing Indoor and Tunnel Routes

Driving at high speed works just as well indoors and underground as it does outdoors, provided you prepare the path first. If you plan to drive through industrial tunnels or along indoor carpets in large castle halls, keep the floor completely free of full-block ledges that could catch your wheels. Use slabs to bridge small elevation changes smoothly, and widen narrow doorways so the 3D frame has room to turn without scraping against walls. Finally, place plenty of light blocks along dark tunnel walls so you can spot upcoming turns well before reaching them.
