Not a bad idea, the gameplay can be fun in simplistic manner. I understand the theme is represented nicely in the context of family is happy in their outing while being unaware of zombies around. Frankly, it can also be portrayed as people do not care if I drive over them.

Sometimes I find it difficult to get in car, it seems I need to be too close to the door to enter. The red overlay on the screen makes it almost unplayable in the most run.
