Picture a self-driving car test in your head and you probably see an engineer or two scrutinizing data... and no one else. Everyday people, if they're present at all, tend to be relegated to the back seat. Volvo is trying something different: it just revealed that it's conducting autonomous vehicle tests with an ordinary family, the Hains from Gothenburg, Sweden. The four-person household is convenient for marketing, of course (we care about people!), but they serve an important purpose: they'll help Volvo understand how non-engineers deal with self-driving tech. How do they react when the car switches between manual and autonomous modes, and what do they do at those times when they aren't taking the wheel?
