had it done several times to me but in one instance it ended ugly (for other guy)...doing 65mph, was on left side of my lane, want to get off at next exit, looked behind see no one, start to get over to right... as i do, i look over to my right to see his "oh ****" expression. he was coming up my lane on right side well over 90mph and was going to pass. he ended up ramming his front wheel between my swingarm & exhaust. i managed to keep calm and upright, he wasn't so lucky. i pulled over, rushed to him. really banged up but was going to be ok. had a hole to bone in knee, rashed back broken arm. i was ok with buckeled exhaust.. think it was learning experience for both of us.....
