I know....same thing, Im in the right lane on I-20, the lane to my right is "lane ends, 500 feet", and I see this guy trying to sneak in at the last minute, I slow down (in my cage) to block him from the rear, he speeds up, I speed up, he comes on over, could'nt get a toothpick between the 2 of us...I finally backed off...Jerk....
