Smart Has People Test Drive a Vehicle While Taking a Lie Detector Test

Smart challenged people to take "the most open test drive in the world" in its 'fortwo cabrio.' This unconventional test drive had drivers hooked up to a lie detector so that they could be asked questions by their passenger. When the system detects a lie, the open sunroof on the Smart car closes and ends the test drive—so the objective is to be as honest as possible and keep the roof open to prolong the drive. Considering that this compact car is marketed as one that's "radically open," the challenge is a fitting one.

Car manufacturers are now making moves to set up inventive test drives beyond the dealership. This is now happening through pranks, partnerships with ridesharing services or coming to the rescue when cars or conditions cannot be driven in.
