I want a mod that allows me to test a route. I'm a bit of a control freak and a big fan of the manual Lane connector of TM:PE. It's quite easy to make misstakes when playing around with lanes that way and I'd want the possibility to test possible routs.
Like this: click on a building or an intersection, select (lane and) vehicle type (car, truck, bus, etc). Select a destination (other building or intersection). Show what route a vehicle of selected type would choose to get between them.
Or tips of any existing mods that let me do this!
