So the driver was either Polish (there are Polish people in Sweden too) or, if he was supposed to be Russian, it has been mistakenly translated to the wrong language. It’s mashiny (машины) in Russian. Though I prefer roboty (роботы), it just makes that caricature Russian sound
I don’t think this is a mistake in the game. The writer Janek is Polish, that’s perfectly Ok. If Janek would be Russian, I think, he wouldn’t say “the Russians” but “my countrymen”.
