It's fun to chat with SIRI, but what if the dialogue could be used to draw attention to a problem? In this case, using your phone while driving. In fact, in the US and the UK, one in four accidents are caused by mobile phone use. Drivers will never leave their phones at home, but the Toyota radio ad solves the problem by simply switching the devices off. The ad engages in conversation with SIRI and asks her to switch the phone to airplane mode. When she protests, the ad's narrator underlines the danger of texting or phoning while driving.
