With luck the former would be good basic knowledge and the latter would be focused on how the autonomous vehicles work, in an effort to prevent road rage directed at your own car.
The only benefit to you in an exit interview is data you can glean from them, and any satisfaction from acting out will burn you in the long run. So get outside yourself and attempt to join forces with the person interviewing you so you both can avoid having to do this in the future. You'll have time for complaining about the bad times when you're with your buddies at the bar.
The ideal exit interview gets to the heart of the problem without pointing fingers. It is impartial, it gets information as often as it gets, and it helps you grow as a person:
It's not "my boss was the worst asshole in the world," it's "I couldn't find a way to improve my work relationship with my manager. Maybe it was a personality clash, but I had taken these steps [insert steps], and felt that my attempts were rebuffed. Can you think of ways I might have done better?"
It's not "you guys are so great I'm so sad and you'll do great," it's "I know we didn't really get along, please be honest, what do you think most damaged our work relationship? [hear answer] Oh, good points, I thought it was also this [insert problems]"
And if you're being polite and constructive and they're they opposite, then ask to cut it short and move on with your life.
