I've always wanted a DECENT transport management program, I wish Rush Hour offered more.
For some reason, I think it would be fun to have the option to choose between things like:
- traffic lights stop signs or round-a-bout at intersection
- how many lanes a certain road has
- traffic light signal timing
- bus lanes
- no parking signs etc.
So far, no such game software exists. Locomotion was addictive but highly flawed.
