As I said, access was considered but Sainsbury's delivery vehicles do not follow the arrangements.
In their planning application they "miscalculated" the increase in delivery vehicles that would result from the expansion; the actual number of delivery vehicles is about twice their estimate. The effect is that if the percentage of incidents per vehicle has remained the same the number of incidents will have doubled.
It is important to point out that the worst offenders are not the Sainsbury's branded articulated lorries but the other suppliers such as Warburton's, Kingsmill, Hovis, Dairycrest etc.
