I heard about the GB experiment - it's not a trial on public roads though. They have a lot of significant hurdles to get over to prove the technology is workable and worthwhile. The install and maintenance costs alone I suspect will kill it unless they can make it just as durable and easily repairable as the existing road surfaces.
