Overtaking lanes in public spaces?

We've all experienced it in public spaces such as shopping centres, airports, stations etc...you're in a rush but it's crowded and you're stuck behind people wandering along or moving slowly with piles of luggage or shopping.

The best bit...the idea wasn't from any clever design agency but a 10 year old!  See the full story and video on the ITV website (http://www.itv.com/news/calendar/story/2014-04-17/new-overtaking-lane-trialled-at-sheffield-shopping-centre/)
