Audio tactile line marking is a combination of line marking and raised profile thermoplastic 'bumps' that make a noise when driven over, providing additional visibilityand safety in low light and wet weather conditions.

Why limit them to just making a noise? They could modulate the bumps so that your car produces a recognisable sound when driven over, like a gramophone record. Imagine veering out of your lane and hearing a loud voice exclaim "Get back in ya lane ya drongo!!" /JK

I like it, but would not want to be driving (or cycling!) next to one of those gramophone lines when other drivers decide they want to hear the whole "recording" several times. They'd wear out very quickly as people try to "play" them.

There's also the problem that most of the time you wouldn't wander onto the beginning of a sentence.
