Following on from my previous thread about making your own car and where to start I've started playing around with some ideas and having a look around the internet for some inspiration.
I’ve seen a lot of amazing concept cars out there that have been designed by individuals not associated to any manufacturers and wondered if you design a concept car can you protect the design or could someone choose to build it? So could someone take a concept design they find and change a certain percentage of the design in order for it to be unique and therefore not liable to be sued by the original designer?
As an example there are 4 Lamborghini concepts below. What is stopping someone taking any of these designs changing them slightly to make it a little more real world and building them? Alternatively if you were to take 25% of the 4 cars and blended them together to make a new concept could I call it my own?
It seems like a bit of a grey area as on one hand you’re using someone’s idea/design but manufacturers in the kit car industry have been copying designs for years with replicas (GT40, Ferrari’s, Porsche).
Any thoughts?
