When in a car with someone else driving, and the driver starts driving over the bumps on the lane divider, you can yell out "Driving Braille!", in an indication that he is driving over the bumps, creating a rapid bump bump bump noise.

(Braille is the bumpy writing that vision-impaired people use to read)
John is driving back from a late concert through semi-windy roads with Jill in the passenger seat, John starts driving over the lane divider which causes the car to mildly vibrate and a rapid bump bump sound to start.

Jill: "Driving Braille much?"
John: "Shuttup I'm tired"

This occurs when someone who is driving on the freeway consistently drives on the white reflectors to guide their path as opposed to driving in the center of the reflector lines. Much akin to a blind person running their fingers over the special bumps to read something.
Hey are you gonna stop driving by braille or what? It's giving me a headache.

"Bots dots" are raised plastic reflective bubbles that are placed on the top and bottom of the white and yellow road stripes, named after the chemist who designed them and found mainly in California. Driving over them results in a thudding that keeps you in lane. Driving by Braille, or "Braille Driving" is when someone is so drunk they navigate by the sound and vibration alone - or worse, lean out the window and feel their way along the road to find their way.
"George Bush was so drunk when he was pulled over, he must have been driving by Braille with one hand on the wheel and one on the road."

Driving drunk or tired until you hit the rumble strip, dirt, bushes, and or small child on the side of the road, then instinctively pull back into your respective lane.

A term used in states where there is no snowfall and therefore there are small bumps or reflectors placed on the road generally on lane lines. Because of this drivers can "drive by braille" by just swerving the other way once they hit these bumps. This is quite convenient when trying to sleep while driving.
Man, it's so foggy all I'm just driving by braille.

When one used the lane markers/bumps to indicate they've gone into the next lane, sometimes causing panic to those in the car.
