The Volvo on This iPad Will Not Run Over Your Finger

McCann Digital teams up with Volvo to promote City Safety, technology that helps drivers brake right before a potential collision. The result is a tablet app called "Finger Safety", in which users' fingeres simulate the unexpected reasons City Safety might be put to the test. Users are asked to place their finger on the tablet's screen in the ad. A Volvo then races in, but no matter where the finger is placed, it stops right before crashing into it.
