Do you happen to observe same traffic jams in same area and time windows as in the real world?

Also, do City Skyline drivers behaving like drivers who would use Waze (or could be configured so that a certain amount do) ?

We see broadly the same chokepoints (Galle Road, Baseline Road, the arteries feeding into Colombo). Modify these and the chokepoints distribute themselves. Small chokepoints don't always appear.

Broadly, if you can do it by fiddling with this: https://doc.tmpe.me/vehicles.html, you can pull it off.
