I would like to see an app to remotely from freecamor your car to kill all other engines on ai cars. Basically remotely control the AI vehicle from freecam to make it a bit easier to make car crash videos. Then instead of having the car you wanna crash just keep on slamming the accelerator, you can either blow it up or kill the engine so it looks more like a real car crash.
I don't think it's necessary though...IMO. If you have the skills, or want to learn the skills, you can make it youself!
