>> The driver was an old white lady that refuses to deliver if a car is blocking the mailbox. Postal policy is 15' of space on both sides of the box or the box is considered blocked. If everyone were to park on front of a box, forcing the carrier to exit the vehicle, then it would quickly turn an 8 hour route into a 12 hour one. Also, the post office views exerting the vehicle as a safety issue. When a carrier exits the vehicle for an unauthorized stop they are creating an unnecessary safety issue and can get in trouble if their management catches them.
