"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."
