What if ups Grounds delivery subcontracted a personal driving company like lift or uber for the approval of PVD down the road? Obviously if that were ever a possibility they would have to implement stricter rules for employment approval and provide tamper proof technology with accurate tracking. But thinking as a consumer, would you want just anyone delivering your package? What if Drivers and pilots were required submission of drug/alcohol tests with something attached to your steering wheel like a BAC breathalyzer (or some advanced un heard of new age technology) every 30 minutes on the clock? Would you still travel under such conditions?
