Adding Camera Motion Blur and Shake Effects Fails

Hello,

Currently i am working on a car game. In this game i am using Realistic Car Controller asset. Here is the issue that i am facing;
- When i add camera shake script to my main camera, the camera only shakes player's car.
- When i add motion blur effect to my camera, it only blurs the player's car.

The camera is following player's car.

I would like to have shake and blur effect to all over the screen. How can i have it?

Thanks in advance.

 

Not sure what you mean here. Screenshots or video would help

 

I'll prepare a video for it and here i'll try to explain it; for instance when i use the cam shake effect on 2D game, the hole screen was being effected when the shake is began. But in this game, the near objects are not seeming like shaking, only the car(the main player which is followed by the camera) is shaking. This shake doesn't effect car's driving.
