A pedestrian fast lane has appeared outside Waterloo station, to help fast walkers get in and out of the station unhindered.
A bit like the escalators on London's Underground system, walkers outside of the fast lane can go at their own pace, whilst those in the 50m lane will be expected to up their speed to 5mph - double the national average walking speed.
The idea comes from Direct Line, which was inspired by the Cycle Superhighway system to create the lane as part of a marketing campaign.
According to a survey it carried out on the UK's pavement etiquette, 71 per cent of the 2,000 respondents felt that there should be separate fast lanes on the UK's pavements, whilst 58 per cent said slow walkers were the most annoying pavement irritation.
Unfortunately, the Direct Lane will only be around for two days, but let's hope it inspires Sadiq Khan to install them in other locations across the city. Imagine being able to speed up Oxford Street?
