The car was invented basically because the order knows that the more advanced technology of transportation that we have available is far too advanced for the current evolution of man. We saw men trying to come up with an effective method of transportation and we had to bring in a scientist from the order to pretend to “invent” the car for humanities sake. We still don’t know how long it will be until we unveil better and more useful methods of transportation to the masses.
This is going to depend on how well the evolution of their “inventions” develop in the next two decades. They seem to be stuck in trying to enhance these vehicles instead of evolving into something new, but we are trying not to get in the way anymore just to see what they can do. Hopefully things will start to change soon and new inventions will come.
