After I got the US roads working, I was very annoyed by these things:
There shouldn't be a "STOP" before every traffic light, the line tells us where to stop.
I have never seen yellow traffic signals, they should stay all black.
There shouldn't be a sign over each lane saying what direction it goes, there should be arrows in the lane when the lane has to turn left or right, but nothing when it goes straight.
I'm not sure, but I don't think making a right turn on red law was added, in the US you can turn right on at a red light if nobody is coming.
I hope these get fixed soon!
