Disagree pretty hard. SciFi has always been a medium for exploring the philosophical and political. Every description of a future dystopia/utopia is social commentary; every alien race is a commentary on xenophobia or cultural exchange. Hell even his own books explore...
If you don't want politics in your books SciFi is probably the worst place to look. Someone should tell him to stick to... idk... character driven romance novels or something.
Simple: try putting it in each hole and if the car doesn't work just take it back out
