I think this company should be refused a license to do business in Tucson, or at least fire someone.Last evening November 30, 2017 I was traveling south on Swan Rd, between Pima and Speedway at approximately 6:30PM. A white van with a unrecognizable dark and aggressive person at the wheel was obviously trying to scare me. The van was painted with the words Driver Provider. The driver followed me so close that I feared for my life as he flashed his lights into the rear of my car and seemed to not stop his aggressive behavior. He was so close that I was afraid to use my brakes. He was threatening to run into the rear of my car and came so close I feared an accident would occur. I was also afraid that if I were to get out and say something that the driver could have and might have caused myself or my wife bodily harm. This continued until I could get out of his way by making a left turn from Swan Rd onto east Speedway. Something should be done when a older resident has to put up with such frightening behavior just to go out for dinner. People like this ought to have their drivers license, if they had one, taken away from them or prosecuted for attempted assault.
