A few years ago, Mustapha Harb realized there was a problem in his field of research about how autonomous cars will change the way people travel. The solution to the problem he settled on was as simple as it was revealing.

Using 13 volunteers (a very small sample size due to budgetary constraints) from the San Francisco Bay Area who owned cars, Harb and his team studied their travel patterns using GPS trackers on their cars and phones for one week, then gave them a chauffeur for a week who would drive the participants’ personal vehicles for them. Finally, the researchers observed the subjects for a final week to look for any changes returning to their chauffeur-less life.
