Stealth drafting normally earns the goofball label, but drafting someone who's doing intervals is totally insane. Stealth drafting someone doing intervals on a MUP is about as nutty as it gets

Yes road, but it still depends on your perspective. If you come across a rider doing intervals but don't know that, then they are going to appear to be riding pretty weird.
And yes, plenty of experienced cyclists do not understand intervals. This place can be proof of that.
