Adding access=yes to a street which has "no motor vehicles" signs (with exceptions) effectively turned Drapery into a through route for all transport modes. However, it did not have access tags which matched the signed restrictions before you edited it either. Hopefully this is now correct.

The Bing street side imagery showing the restriction signs is at https://www.bing.com/maps?toWww=1&redig=0E61462A315B4089ADF0DBB49CFAA9E5&cp=52.238538%7E-0.897411&lvl=19.8&mo=om.1&pi=-11.1&style=x&dir=136.9
