If you were traveling 60 mph and not wearing a seatbelt and collided with a fixed object how fast would you be traveling when you hit the windshield?

Well, honey, if you're traveling at 60 mph and not wearing a seatbelt, you'll still be traveling at 60 mph when you hit that windshield. Seatbelts aren't magical speed reducers, they just keep you from becoming a human projectile. So buckle up, buttercup, safety first!
