All headlights are adjustable; so that dealer is smoking something, or rather just wants an "over-educated prius owner" out the door and to stop bothering them with minuetia. Seems like many service departments want us to be like Camry sheep and just let them run roughshod over our vehicles. But then again that is a topic for another thread.

I do not get high beam flashing in city driving. But on unlight rural roads, I get a couple each week. Yes, I flash back to educate them. However, I'm pretty sure that in my area flashing high beams to oncomming cars is not legal. It poses a pretty significant safety issue, especially if somebody is temporarily blinded by the flash of somebody elses highbeams. I seem to get the flash most from people in GM SUVs. I'm not joking, it is like they have never seen effective headlights before.
