Imagine that you and a few friends are in your car driving to the movies. Everything is going well, and you enter the freeway to make your final trek to the theater. While you are on the freeway, another vehicle comes barreling across multiple lanes and cuts in front of you. In an attempt to avoid the collision, you quickly hit the brakes -- but it isn't enough. You and the other vehicle collide, and the accident sends both of you careening into the railing.
Thankfully, no one is seriously hurt. There are plenty of bumps and bruises to go around, and maybe a bit of whiplash too, but everyone escapes serious injury.
