from ur statement as u mentioned above..it is understandable that u were on wrong side..go to left from middle line is always wrong..it happens always with me.as i use left line to go straight at round about, but always notice the position of the side car,,mostly cars use indicator if they want to go to left from middle line.if u r clever,than u can notice this .and can give him way to cross u and thn u can go to straight..only few seconds game..
