My solution: if there's nobody behind you...stop. They assume, consciously or not, that you will change course for their benefit, but you can't change course if you're not moving. Suddenly, you become a stationary object, and they will adjust to that. I've never had people blunder into me when I've done that, and I've sometimes noticed them correct their walking formation afterward.
