Why do babies have to face backwards in the car?

Until recently, I was just a dope about this! They say that you are more likely to have a frontal crash, so you should face babies backwards. I just assumed that since you become a parent, you are more likely to be distracted and looking back at your kids so you crash more than other people. Then I finally realized that there are a lot of things the front of the car can hit besides other cars, like trees, telephone poles, etc. The only thing that can hit the back of the car is another car (unless you are backing up and Claire parks in the wrong place). So chances are someone may hit something else besides you. Besides, you are so much more distracted!!
