Bristol had an earlier abortive system with Lasers on buses and
bar-codes on Lamp posts. Unfortunately Lasers shook themselves to
pieces and buses had to be out of service for repair as no 'modular '
construction.
Less than a third of the buses carried lasers and most of the bar codes
were turned around by the ****, sorry children at the time.
