It's very annoying when your character gets stuck under a burnt out Corvette or Mobile. Then you have to blow your way out. Also, enemies trying to kill you at the same time really helps a lot.
My solution is to just make destroyed Corvettes and Mobiles fade away like the Hound Walker does when it gets destroyed. Simple, easy, effective.
As for drones, they're too tiny and easily movable; it's very hard to get trapped under one. And Life Capsules, ropes, and crates are sorry excuses for vehicles (so they don't count).
