In this work, the performer “rides” a typical wheeled office chair, sliding down gentle slopes at various locations, such as a typical city street and in the countryside. This work is reminiscent of The Measurement of Friendship in several respects. In The Vehicle, the performer plays a game of roller coaster, and the game involves the effect of vertigo and chance. The title implies the parodic use of a vehicle, creating a comic effect, because this vehicle looks ridiculous—even absurd—reminding us of a“vehicle” road test. Unlike The Measurement of Friendship, The Vehicle measures gravity and acceleration. The performer allows gravity to control his speed naturally since he does not touch the ground or other objects to influence his speed or direction during the rides. Both works measure the natural force of gravity on different orientations: The Measurement of Friendship on right/left, and The Vehicle on up/down. The Vehicle seems like an ironic experiment with the acceleration of gravity on the body’s movements. During this “road test,” there is no other traffic, and the “chair vehicle” is completely controlled by the body and gravity.
