Smart promotes ForTwo Cabrio test drives by lie-detecting anyone brave enough to get behind the wheel

Car maker Smart is going big on transparency in its new campaign for the fortwo cabrio.

The auto firm invited to public to participate in a lie-detector drive, which it branded the world's most open test drive.

As part of a campaign devised by BBDO Germany, the test drive immediately ends if the machine detects a lie.

Questions are asked by a second passenger, promoting the ‘radically open’ city car.
