Tiny Road Mat Quiet Bag

 I actually don't have an image of this folded and holding the cars but I promise you it does and fits nicely into a handbag to take anywhere.

 Simply sewn to fit "Learning Resources" mini motors, but you could make this for any cars you have available. The landmarks on the map serve as a great parking parking space for corresponding motor (bus- school, fire engine- fire station etc.) which was not my intention but works well!
