Overlapping sidewalk of taxi/car/bus stop

Feature request title:

Overlapping car stop / bus stop / taxi stop sidewalk


The car stop, bus stop and taxi stop all come with their own sidewalk attached. However the sidewalk sections of multiple stops cannot overlap. This leads to doublewide sidewalk if the stops are back to back.

A possible solution would be to remove the included sidewalk from the stops and to ask for a sidewalk to be connected to the stop similarly to how a road must be connected. Alternatively it would be nice if the sidewalks could be made overlapping with other sidewalks.
