Watch these videos to see what it's like to crash a car or bus into another vehicle, a brick wall, or a wrecking ball. Each video starts out showing a collision at 5 to 7 miles an hour, then re-runs the simulation at increasingly higher speeds, usually ending at 300 or 400 mph. Here are a couple of my favorites:
School bus hitting a van parked against an immovable wall:
Car hitting an indestructible bollard:
Car hitting an iron ball hanging from a chain:
School bus hitting an indestructible horizontal beam:
