Sun Visors

Dear California Drivers,
On your morning southbound commute, please anticipate using your visor (that thing on the roof above your steering wheel). Every morning I run into the same issue...the Sun. It appears over the mountain and looks all of us right in the eyes...I understand it's bright, but that's what the sun visor is used for...to block the sun. There isn't a need to slam on your breaks and jack up the rest of traffic for your stupidity.
Sincerely,
Michigan Driver
