I don't think it would be possible to truly blind a motorist who's got 3000+ lumens of automotive high beam. They're not going to lose their position on the roadway, they're just going to wince and figure out courtesy is a two-way street (haha).
Seriously though, I doubt the offenders even compute "oh, that's a human being with eyeballs, just like me. I need to dim my headlights for them, regardless of their ability to high-beam me back or not." And some may kick the high beams on just to verify what the heck it is.
