Really fun game!
1. STOP sign, and make people go slow instead of stop at the yield if there is nobody there - so we can have 4-way stops where people don’t complain (nobody complains at 3-way yield) and to have more options to enhance your city!
2. Speed limit variety - Like 20, 70, etc.
3. Stacked signage - so that if there is a small gap between intersections and you want to block 2 or more directions, it is possible.
Have a great day!
