I know it’s not possible to build a driving simulator to drive you’re own cars within this project. But on the other hand it wouldn’t be necessary to build an own simulator.
I don’t know how different you’re models are but what about an export to Rigs of Rods (I know it’s not the best simulator and driving game but then it is a simulator that is already there).
And I am sure it would be some advertisement for Automation and maybe it would be supported by the Rigs of Rods team as well.
Anyway hope to play the demo soon (order already placed).
