This trophy is very easy to accomplish and you can get this as soon as you unlock the Stingray vehicle which is a part of the main story line.
Janey Springs will send you to a building that requires you to input the password 8-0-0-8. This building is in the Triton Flats area.
You will then be able to spawn Stingrays from any vehicle location and drive them instead of the Moon Zoomy.
To earn this trophy, find an enemy, hold
to levitate in the air, and then press
to smash down and crush the enemy. I crushed a bandit just outside the vehicle spawn point to earn this trophy, but other videos I've seen have them crushed Scav Moon Zoomys. So it appears this trophy is not limited to enemies on foot, but also within vehicles.
