This is a mod that prevents you from crashing your car. Here is how to use it:
When you are about to lose control of your car, push and hold space bar. Your vehicle will lock in place and completely stop moving. Then, push the brake to stop the wheels from spinning. Lastly, release the space bar to unlock the position of your vehicle. Then you can keep driving.

I do have a fix for the items flying out. If you use the inventory mod and set it to maximum capacity (50 items) you can probably carry everything and it won't fly out.
