The term 'HITCHHIKER's Need' refers to the three things a HITCHHIKER needs in order to get from one place to another: a LIFT, a RIDE, and a THUMB. A LIFT is a form of transportation, usually provided by a stranger, that takes the HITCHHIKER from one place to another. A RIDE is a longer form of transportation, usually provided by a stranger, that takes the HITCHHIKER from one place to another. Finally, a THUMB is a gesture used by a HITCHHIKER to signal to passing drivers that they are looking for a RIDE.
