Driveway

A driveway is an object in The Sims 2: Nightlife and The Sims 3. A downloadable version which does not require Nightlife is available for The Sims 2 players who do not have that expansion.

In The Sims 2, a car must be placed on a driveway or driveway extension. The driveway is very large (taking all tiles that a Sim needs to enter the car) and must be connected to the street. In The Sims 3 the driveway is small and can be placed anywhere in the lot.

Horizontal Driveways
During normal build mode, the driveways are always placed vertically. However, there is a cheat to make that vertical driveway or driveway extension become a horizontal one.

First, enter the ever famous moveObjects_on cheat in the cheat box (prompted by pressing ctrl + shift + c). The sidewalk of the lot across from yours becomes customizable. Delete the sidewalk there, then go to DRIVEWAYS in the build menu. Choose whatever kind of driveway you want and when you place it on the lot, it is now in the horizontal direction.
 * Only use this for driveway extensions
 * The garage doors also become horizontally oriented.
 * Cars will still park in the vertical driveway, not the extension in the horizontal orientation. (Still trying to figure out how to fix this)
