Last night I was driving down a rural road and was in no hurry. A car
pulls up behind me and his headlights are absolutely blinding me in my
mirrors. This car is keeping a reasonable distance behind me, but those
lights are extremely annoying. I began to wonder if he had his brights
turned on.

I flipped the rear view mirror to the "night" setting, but my side view
door mirrors can not be adjusted without rolling down the window, and
since it's a hassle to readjust them, and it was cold last night, I was
not going to open the window and adjust it, which still leaves the right
mirror on the passenger side.

Anyhow, the headlights on this car behind me were much worse than most.
I finally grabbed a piece of paper and held it against the side window
to block the mirror, thus causing me to steer with one hand.

I finally got to a stop sign where I had to turn, and saw that car was
turning the same way as me. So I immediately pulled over to the shoulder
to let that car pass me. SURPRISE.... It was a sheriffs car!

What kind of lights are they using? Whatever they use, they are
dangerously blinding for other drivers. This is not the first time I've
had a vehicle behind me that has extremely bright lights that blind me,
and it's turned out to be a police vehicle....

Police or not, those lights are too frikkin bright!
