How do you think momentum affects car crashes?

Scenario:

1 cars and 1 truck are headed straight for each-other both going 60mph however the the car weighs 2 tons while the truck weighs 5 tons. Once the Automobiles crash into each other the truck will push the car to the direction it was going since it has more energy in the crash. at the same moment of the automobiles crashing the people would theoretically carry all the kinetic energy in them and fly out the wind shield with around the same energy of the moving automobiles
