I didn’t knew about gyp either until a couple years ago. Never saw it spelled.
Did you ever read the Seven Habits? I think treating like he is incompetent is the wrong way to go. Correct him as needed, if needed. If he is conservative (which does not mean racist, misogynist, potential rapist as you implied @Emsmom1 - actually that is a really offensive (the irony), try smaller government, personal responsibility…), he’d have to be exceptionally brave to have a vocal opinion on a college campus. He’ll find that out quickly enough. We’re tolerant about everything except ideas. If he is socially offensive/awkward or amoral ( which is not the definition of conservative), you won’t be able to correct that in a car ride. Bond with him as a person and he’ll turn to you as someone he can trust in time of need. As a conservative he’ll probably face quite a bit of microaggresion and need someone to turn to.
