I'm working on a simulator of old USSR transport.
But my boss is telling me that I can't put real names on vehicles, but don't get me any proofs of it. I know that you can't put real human names and company emblems, but I didn't find any info on transport names. I often see real-life naming in other simulators, but they come often as mods (exception is Subtransit).
Any thoughts on it, is he right or wrong (I don't intend to use logos of the transport)?
