Mazda's press release concerning this vehicle:
The Secret Hideout compact concept vehicle is designed to capture childlike thrills and excitement in a vehicle and recreate them in the hearts of today's young people. Young people today are searching for something simple, gentle, friendly and relaxed. They choose from the sometimes confusing array of goods and information available, and coordinate their choices to create their own unique identities.
The Secret Hideout is designed to provide young people with excitement as well as a personalized retreat in which to ease the mind and heart. For that purpose, development aims included: a simple, friendly and warm design; a handmade feel focusing on individual details; and components that allow individual selection and coordination.The Secret Hideout might have been designed to "capture childlike thrills and excitement" but I think it would have been every parents' nightmare.
