Especially if you're driving up behind someone and taking your dear, sweet time to pass them! All I could see in both my rear view mirror and my side mirrors was a blinding, bright white! Thank god all I had to do was keep driving straight, because for a good 15 seconds of driving at 100km/h, I could hardly see a thing except your headlights, let alone the fuzzy aftermath you get after having a light shone/reflected into your eyes.
I could have been a jerk too, and flicked my high beams on as soon as you pulled in front of me after passing, you know. —Blinded
