Teardown

it might be a bit overkill, but heres how I got this achievement
I used the jetpack mod and the hook shotgun mod (available in Mod Pack #1 in the microsoft store)
Enable both mods, but on the hook shotgun mod, go to options and turn the hook pull power to maximum.

Go to any map, I picked Villa Gordon
Use your hook on the car and fly away with the jetpack
then pull the car towards you and get in the car at the same time

If the clip ever gets deleted then let me know

The way I did this as follow:

Go to the settings/options, Go to the "Game" tab. go down to "Enable Spawn" and activate it. This means you can spawn or "draw" Voxels on any map.

Go to any map, can be on Campaign or Sandbox, pause the game and push to bring up the Creative Mode, fly up a little using the button and look directly down, increase the brush size to its max using the and then draw a column of Voxels as high as you want (the higher the better), draw more Voxels to make a platform, push the to get out of draw mode, push again and then push to go to the "Spawn" menu, use the "Built-in Mods" go to the "Car" category" and select any car. Place the car by pulling the on the platform you have made, get in the car and then drive off the edge. if you're high enough you'll simply fall for the needed 2 seconds and pop the achievement

If you can't draw and more Voxels, simply destroy some buildings or other things to free some up

(I know its a bit long winded but i felt it was the easiest way for me to do after trying loads of other ways)
