How does the car not explode when it lands on its roof from such a height. I have seen my cars in GTA5 explode from landing on its roof when it jumped over the little train rails hill...
I always did this by adding car to "Entity Database" usings "Spooner Mode" in Menyoo Trainer or spawn vehicle using "Spooner Mode".Or by spawning vehicle by Add-on spawner with "Enable persistance" option. This also prevent wheels from get stuck. But now I use a Zolika1351's Trainer that simply disable this in Options > Game Tweaks > Gameplay > No Falling Car Explosion to On
