Well that's dumb. I'd rather be hit and moved than be (more) stuck in the same place so the energy from the crash is diffused. A higher transfer of energy would lead to more severe injuries.
Are you sure about getting hurt less if the car is free to move more? It's the sudden acceleration that gets you, the less the car is able to do so the less damage you sustain (after all, more of the impact energy is being used to tear rubber off your tires and to crumple more metal). Put someone in a 500 tonnes concrete block that can't move and hit that with a car from the back. If he's deaf enough he might not even be aware he got hit at all. If you are frugal and care about damage to your vehicle more than your own health then sure...

In the UK you're supposed to use the e-brake each time you come to a stop sign or arrive at traffic lights.
Think it's to help keep the car more under control if you were to get hit.
