Generally eye contact when driving is pretty rare since you're watching the road. As a passenger you should look anywhere you want.

That's what I love about talking while driving. Eye contact is in no way expected or appropriate.

Eye contact is not needed, however it’s polite to turn your head towards the driver when you speak to the driver, rather than facing the right side window. The driver does not keep their head fixed facing forward, sighted people have peripheral vision, which gives them a chance to angle their face your way without issue.

Even when I can tell the driver is trying to look at me, I keep my head straight forward. It freaks me out that someone wouldn't look at the road at all times.

I prefer the driver to not look at me while they drive, and I do not make eye contact while driving. I know two people that feel they must make eye contact whenever talking, and this includes looking in the rear-view mirror to talk with people in the backseat. It's bizarre to me, and the do it 100% of the time.

PS: I refuse to make eye contact with them so stare the opposite direction out the window to try and suppress their behaviour :)
I find this is a personality trait and fairly rare.

I tend to sit in the back of the car but on the rare Kasians I do sit in the front, I don’t try to make eye contact.
