"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.
