What the available statistics say
Using DFT figures, from 2007-2008, 60.7 pedestrians were killed on the pavement by motor-vehicles, whereas 0.5 were killed on the pavement, by pavement cyclists. This is based on 10% of pedestrian casualties being on the pavement or verge as was the case 2007-2008. The ratio of pedestrians killed on the pavement by motor-vehicles to those killed by cyclists is therefore 121.4:1. The ratio from 1998-2008 is 820.1:3 or 273:1 (uses the same 2007-2008 10% pedestrian casualties figure).
