1) front and rear-facing dash cams to defend against damage claims 2) configure cars to track phone usage, time-stamped, and downloadable thru the OBD port. If driver is sole occupant, some use of phone would be provable. No good for off-line activity, like games. Obvious privacy issues like other OBD data. 3) Pedestrians need an app for the “self-walking phone” with sub-1-meter location accuracy that flashes green man, or yellow or red hand when phone-obsessed user is about to step off curb into cross-walk or traffic.
