Especially here you can observe the attention to detail. So there are entire scenarios when the fire brigades go out on their missions - in addition to blue lights and sirens, the cars steer through a traffic jam, drive to their locations, turn off the blue lights when they drive back to their stations.
If you look closely - the lamps on the vehicles can be controlled individually - the vehicles also flash when they want to turn - it's the little things that you should watch out for.
You could certainly spend half a day in Wonderland just to watch all the operations day and night and marvel, marvel, marvel...
