Tagging on from this and that ad, be careful about UFO's in the car. Books, handbags, full water bottles and unsecured pets all turn into lethal flying weapons under high speed braking. Secure them or put them on the floor and make sure that ickle pups aren't allowed to wander up and down the rear parcel shelf looking cute or sat unrestrained on a passengers lap or on the seat. You will kill them in a very nasty way if you have to brake hard or are in a collision and they may kill you or a passenger as they fly and die :-(
