In my simulation I have vehicles that sometimes need to go into 'wandering'
state, so I generate random routes for them in runtime using a loop of
*random.choice(e.getOutgoing())* (where 'e' is the previous edge in the
route).
It does lead sometimes to vehicles driving in circles over opposing
directions of the same street but this is fine for my purposes.
Why is it then 'suspicious' and is there a better way you suggest I use?
