Ron Dennis also left school around 16 or so... We have two strong role models, Sir Frank and Sir Ron
To be an engineer you need to study at an University. As simple as that. I don't care about "honoris causa" or other kind of recognition.
Don't get me wrong, uncle Frank and uncle Ron know a lot about F1, and it is because they've been around for ages; they might deserve an honorific degree. But there are other people that gets them for other reasons (I'm talking about the "lamb") and it doesn't mean they deserve the title.
