Shouldn't test vehicles have at least the same level of attention monitors as current auto pilot/assist vehicles do? For these specific vehicles shouldn't they have some hand placement sensors or wifi strength detectors or mobile signal detectors or eyeball monitoring at a minimum? Or use a custom app to "lock" the phone while driving, exit app and the car pulls over. Not that the driver would have prevented this incident, but seems like a logical requirement.
