Consider a scenario where I'm thinking of building an automated driving system for my own learning, I use driving simulation video games to aid a specific computer vision module as a test bench since I don't have the financials to actually hire a fleet of vehicles and land.
Is this considered fair use? If later on I'm successful in building the system and I want to commercialize it what legal issues can arise?
What if I decide later on to use portions of the software for another commercial product?
