An electric vehicle with partitionable frame includes a chassis assembly, a head tube, a front wheel, left and right rear wheels, and a seat. The method comprises a method of spatial filtering, a method of temporal filtering, and a method of performing the spatial filtering and the temporal filtering sequentially. The different optimising nodes’ collections of end-user nodes are at least partially coincident such that each optimising node can determine a different routing modification with respect to at least some of the same end-user nodes.
