Up to 4 visitors to the Mazda booth were handed out smartphones with the app preloaded, and the “racecourse” was projected onto a large screen so that everyone is able to have a bird’s eye view of the entire situation. Once the light turned green, it signalled the moment to burn some of the proverbial rubber on the asphalt! That would involved a healthy amount of vigorous shaking using your hand, and it is a race of endurance as well as strength, so make sure you have had a breakfast for champions before giving it a go! I am quite sure that there is an optimal way to figure out just how much shaking is required to hit top speed.
