"This happens when a design the has been circulated on the Internet. Public Domain.It grabs attention. You might find those who actually can't actually design... try to take credit for an idea they see. That is the world we live in.Our Mini Modal taxi cab was used many times with-out permission. Oh well..However, it did do the service of creating enough awareness to re-design the NYC taxi. So it served its purpose. It should be stated that those who use work or show it as their idea... should give credit and support the origins of the concept. That is timeless."
