The vehicle sims are a set of six simulators located directly to the north of the mainland sandbox sims: Balance, Bethel, Briliant, Fame, Fortuna, and Georgean. They are Linden-owned and are the "official" designated place for residents to test out vehicles; on most days they're set up with a race track, lots of open space, and some water for boats.

Linden Lab formerly rented (or for offical Linden-sanctioned events, loaned) the vehicle sims out for large-scale events and expositions. Notable examples of this in the past include the SL Relay for Life, the Second Birthday Event and Third Birthday Event, Gay Pride week events, and the Scripters Trade Show.
