2016 Subaru Impreza merges onto highway. Downshifts and accelerates instead of yield. Had entire right lane open. Decided to cut 2 lanes to left, hit me in middle lane (oops - turns on blinker), car in left lane beeped the horn at him, then merges back into middle lane, driving at traffic pace.

Maybe he didn't check his blind spot, or intentional.

Open to criticism.
