driver van (160009 SD16 ), license plate # 55263T2 . This van was parked illegally in front of a white curb (passenger loading & unloading ONLY ) . It was on Bay State St . in Alhambra, Ca. on 07/16/21 apprx. 1:25 P.M. The problem is, the van was stopped in front of the mailbox letter drop . At least 10 minutes elapsed before the driver (with no concern for others), returned to the van & drove away . I know Amazon drivers are under a lot of stress, but compromising other vehicles safety is unacceptable
