A touch of the same ol same ol? I think those kids knew quite a bit about formula 1 by your description.
Yes, in a certain shallow, superficial, and totally naive fashion they did. And they also had a great deal of confidence in their views as well as the profundity of what they were saying.
But if they had any brains at all they should keep their mouths shut and ears (mind) open when speaking with those who have actually driven the cars, neh? You just never know whether you're speaking to someone who might actually have direct, personal experience with the very things you've never seen or done. Such speculation often ends up sounding like a bunch of 14-year-old speaking out of their hind regions. Which is sometimes rather endearing in an enthusiastic 14-year-old. Not so much in a grown man who you'd think would know better.
