Firing Rocket From A Car

Hello Everyone,

I'm trying to make a car fire a rocket like in a death race movie. When Rocket is fired I want it to stay in front of camera for a while and then Accelerate towards the target. Either it moves towards the target or move forward and destroy any other car in the way. I've used Wheel colliders for car mechanics. Please suggest anything that could lead me to the required functionality.

Thank you so much in Advance.
