[quote author=Squashed_Fly link=1361444348/22#22 date=1361782553]If you are unobservant, and haven't seen a car in your mirrors (or a bike), you don't need to indicate. Personally, that's why I always indicate - its a good habit to have for the very reason you just outlined.
But if I'm crossing lanes on a motorway, and I can't see anyone close enough to me to be affected by my actions, then usually I wouldn't bother. I can't see why you would be changing lanes if there's no one around you? If you're moving out to overtake or moving back in after overtaking then surely there are others around who need to see an indication of your anticipated move across the lanes? /quote]
