"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."

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.
