I agree, the cars are useless. You can't even drive them.
I don't get this theory lol
You can't get a newspaper out of the dispenser....
You can't fire the cannon....
You can't sit on the benches....
You can't play with the tether ball....
You can't swing in the swing set.....
You can play on the seesaw....
You can't water the flowers....
You can't ride the escalator....
You can't pick apples from the apple tree....
You can't sit in the lawn chair...
You can't do anything with the butterfly tent...
You can't make a call in the phone booth...
It's all about making a realistic looking town. A town without cars?!
