Road rage and possible DUI. White male driver aggressively coming up behind me and tailgating me very closely while I was on my motorcycle. I change lanes to let him go but he moves lanes after me to stay behind me and keep threatening me with his car. I end up moving over to the shoulder to let him go. He followed me into the shoulder and got very close to me until he close-call passed me. He was screaming f you and seemed drunk.
