Vehicle Template with Thruster Configuration will be affected by force relative to the distance from the origin

Vehicle Template vehicle with added Thruster Configuration to its VehicleMovementComponent will be affected by force relative to the distance from the origin. At around 200000 the force is enough to accelerate the vehicle independent of the user input. I've mapped the distance vs acceleration:
Distance Acceleration
0 0,1
10000 5
50000 25
200000 73
400000 207
500000 273

This only happens when there is a Thust Configuration on the VehicleMovementComponent.

I'll add the utrace file to the report in case it is useful to the debug process.

Steps to Reproduce
I recommend using the provided repro project for easiness of reproduction. Simply run the Case18129043 project and PlayInEditor to see the spawned SportsCar moving on it's own.

Doing from scratch:
Create a VehicleTemplate project
Create a new map
Delete the floor
Add a large flat landscape [ around 100km x 100km ]
Setup WorldSettings so the DefaultPawnClass is the SportsCar_Pawn
Edit SportsCar_Pawn and add a thruster configuration - just pressing + and leaving at the defaults
Move the PlayerStart to (X=200000.000000,Y=0.000000,Z=50)
PlayInEditor

Expected result: the car should not move on it's own
Actual result: the car moves on its own.
