You missed the centripetal force of the orbit they're in :)

Not a great analogy. The cars do kinda jitter and freeze, as cars == data packets, or somesuch.

better analogy would be that they reckon the stock exchange stops working... then again with no traders it might.

This traffic analogy is broken.

How about if there's traffic on the roads, all doors to houses & offices will stick, only open to admit an arm, or be welded shut?

I don't mean to down the kid, he deserves kudos for doing the work.

BUT. I agree with parent, the basics of this idea is pretty similar, and they've been tryingf to grow 3d nanocrystals for years which has yielded few practical results. all this kid did was some research, he hasn't built a prototype, hasn't proven the principle, nor worked out all of the engineering challenges that will inevitible come up.

So I get annoyed when a lay-mans armchair idea as parent called it gets lauded as brilliance when all the real challenges of *making the damn thing work* are still ahead.
Now get off my lawn!
