Driving on the road requires attention and focus, and unnecessary activities like listening to one’s phone, watching a movie, and even eating can be fatal. Another habit that could be considered as the biggest risk factor while driving is wearing headphones or earphones. A study in this regard conducted by the US-based auto manufacturer Ford on such a scenario under controlled situations had astonishing results. ALSO READ Ford used data collected from more than 2,000 participants immersed in a virtual environment. The researchers developed an application called Eight Dimensions (ATD) for the experiment, which used road sounds such as the whooshing effect produced when a car travels at a high speed, and the siren of an ambulance.
