The Musical Roadway was indeed an experiment BUT not by Imagineering. Tim Sprunger of the former Disney MultiMedia Group, invented the concept and made a removable one foot by 100 foot strip which had small raised ridges spaced to create an vibrating tone. For test purposes you would approach the strip at about 30-40 mph and pass the driver side tires over it. Tim made a video of this using my White Firebird. It seems nice wide tires sounded best. His plans would have had permanent ridges applied all the way across several locations on World Drive and Epcot Drive, made of epoxy and special grit for all for wheels (surround sound:ROFLOL
Tim tried to get Imagineering interested but they wanted to own the patent and give Tim a token fee and cut him out of any involvement with his project. Needless to say he still has the strip (he keeps everything) and probably the video. Tim is a incredibly creative artist, musician and inventor and lives in Kissimmee.
