Research on implementation of vehicle model running in Unity

General information for the business: Autonomous vehicles
Kind of development: Customization of existing program
Description of every module: We are looking at whether Unity 3D is the best platform to implement a simulation environment for testing autonomous vehicles. We would like to hire an expert for a few hours to help define what we could use off the shelf to put a vehicle model into the Unity world, import existing LIDAR data and control the car externally with an NVIDIA PX2 autonomous system.

We are hoping that an expert on Unity who has had experience of implementing a car racing game on the system could write a small piece on how this might all fit together and what things we could take off the shelf and start.

Basically we want a spec for implementing this system.
Description of requirements/functionality: Define a specification for implementing a simulation system in Unity
CMS and Admin requirements: Unity
Specific technologies required: Unity
