The space between the front of the car and your face is really irrelevant. The real problem arises if/when the deer comes through the windshield! But remember, the smart is a much narrower than the usual car, and more nimble. There is less of it to hit the deer, and that makes it slightly less likely to make serious contact, and avoiding the deer strike is easier due to the nimble nature of the car. For those reasons alone you're actually better off in a smart!
