You can make 3 improvements to TS4 to perfect it. What would you improve?

I know you said 3 but these two below I believe could actually make it in the game with an update...hopefully:
1. Entering the neighborhood and it reflects day or night time
2. Return of the school bus, work car, or social worker car actually appearing in front of the house instead of sim disappearing into thin air & the return of cars & garages even though they will be more similar to TS2.
