Such a sad story.

It is unimaginable what that must be like for the family.
Everyone going to prom, I urge you to be extremely safe in everything you do, especially driving. Don't bother your fun night with the burden of driving. Hire a professional driver, your life is worth the cost.
There was another similar incident just the other day in Orange County, CA

When I heard about this one, I actually considered switching to driving a safe sedan type car, rather than a lifted truck (which I currently drive). The photos of the people and parts of the SUV laying all over the road were just astonishing.
If I ever find myself in a position to make/influence laws, I would definitely make stricter driver training/testing/education requirements as well as improving vehicle standards. Lots of accidents are caused by people not knowing how to handle a situation. And if race car drivers can walk away from a 150+ mph crash, there is no reason the public shouldn't be able to as well.
