Here in Oz we have what is called the Red Plate scheme.
Probably came about when it was considered by the pollies that a 25 year old bike wouldn't have pulled the skin of a rice pudding but now days it's a little different.
Hopefully the state regulations on collector/antique plates are more relaxed than here where I am at.
You put an atique plate on here and you are only allowed to operate it in a parade or special event.
Not allowed for regular day to day driving.
