Vote up from me, but even this isn't optimal. As opposed to fire trucks, ambulance vans can be parked almost anywhere in the city waiting for calls. They don't need to wait at their base station. They get faster to a call location than a fire truck.
In 99% of US jurisdictions, you cannot even develop land in a way that prevents an enormous firetruck from driving all around the property. Which means less density, more wasted space for road, further cementing a car-centric life.
